My twelve-year-old twin daughters, Emma and Alice, had always shared the kind of bond that only twins seemed able to understand.

They argued about clothes, snacks, bathroom time, and who got the front seat, but five minutes later they would be laughing at some joke nobody else could understand.

When school began again in September, I expected complaints.

But by the end of August, they were obviously ready to come home.

Instead, they were excited.

They had spent the entire summer with my mom, who lives near the ocean, and they loved staying there.

Grandma spoiled them, allowed them to stay up too late, and somehow persuaded them that pulling weeds counted as “gardening adventures.”

But by the end of August, they were obviously ready to come home.

“I miss my friends,” Alice confessed.

The first several school days went smoothly.

Emma rolled her eyes.

“You mean you miss Olivia because she always packs extra treats in her lunchbox.”

“Same thing.”

Emma laughed.

The first several school days went smoothly.

After two months without them, it felt good having my house noisy again.

They came home talking about new teachers, cafeteria drama, and which classmates had changed the most during the summer.

I remember feeling relieved.

After two months without them, it felt good having my house noisy again.

Then, one afternoon, my phone rang.

I was at work.

“Is this Emma and Alice’s mom?”

The caller ID showed the school.

I answered casually.

“Hello?”

A woman spoke.

“Is this Emma and Alice’s mom?”

She sounded as though she was struggling not to cry.

“Yes?”

“This is Ms. Harris. I’m Emma and Alice’s math teacher.”

Something about her voice made me sit up straighter.

She sounded as though she was struggling not to cry.

“What’s wrong?”

“Emma suddenly became very ill during class.”

I stood so quickly my chair rolled backward.

My stomach dropped.

“What do you mean, ill?”

“She said she felt dizzy. Then she collapsed.”

I stood so quickly my chair rolled backward.

“Where is she?”

I barely remembered the drive.

“We called an ambulance. They’ve taken her to St. Mary’s.”

“I’m coming.”

“I’m so sorry.”

I barely remembered the drive.

I grew frustrated at every red light that slowed me down.

Alice was already there with the school counselor.

At the hospital, someone directed me toward the emergency department.

Alice was already there with the school counselor.

She ran straight into my arms.

“Mom.”

“Where’s Emma?”

Alice shook her head.

Nobody could tell me anything useful.

“I don’t know.”

Her face was pale.

I kept asking nurses for updates.

Nobody could tell me anything useful.

Everything felt like a blur, while time somehow seemed to move through molasses at once.

Then a doctor walked through the doors.

I knew before he spoke.

He looked exhausted and sad.

I knew before he spoke.

“I’m sorry.”

I couldn’t breathe.

“Her heart stopped suddenly. We attempted resuscitation, but unfortunately we couldn’t bring her back. Is there any history of heart defects in your family?”

“No. She’s only twelve.”

I stared at him.

“No.”

“I’m very sorry.”

“No. She’s only twelve.”

He didn’t respond.

After that, everything moved past me in disconnected pieces.

I remember my knees touching the floor.

After that, everything moved past me in disconnected pieces.

Forms. Phone calls. People bringing meals. Teachers sending flowers.

For a few seconds after waking up, I would forget.

My mom arriving and crying so hard she could barely speak.

The funeral. Then silence.

The hardest part was mornings.

For a few seconds after waking up, I would forget.

Alice was the only reason I got out of bed.

Of course, once I remembered, the grief came rushing back all at once.

Alice was the only reason I got out of bed.

She became quieter too. She stopped sitting in Emma’s usual chair at breakfast. She stopped watching the shows they had enjoyed together.

A week after the funeral, the school called.

She slept with her bedroom light on.

I tried talking with her.

Sometimes she answered. Sometimes she simply shrugged.

A week after the funeral, the school called.

They wanted me to collect Emma’s belongings.

Eventually, Alice came with me.

I couldn’t face it, so I waited another few days.

Eventually, Alice came with me.

A secretary handed us a box.

There were textbooks, notebooks, a sweatshirt, two pens, and Emma’s water bottle.

But there was no backpack.

“Where’s her bag?” I asked.

“We thought you had it.”

The secretary frowned.

“We thought you had it.”

“No.”

She checked with the classroom teacher, the nurse’s office, and lost and found.

Nothing.

I didn’t have the energy to continue searching.

Alice stood beside me with her arms folded.

“Maybe it got lost when the ambulance came.”

“Maybe.”

I didn’t have the energy to continue searching.

A missing backpack seemed insignificant compared with everything else.

A month passed.

Most days, everything felt automatic.

I was still struggling to function. I returned to work. I made dinner. I did laundry whenever we ran out of clean clothes.

But most days, everything felt automatic.

Then yesterday morning, I decided to clean the house properly.

Eventually, I reached Alice’s room.

I’d walked downstairs, stumbled over a stray sweater, and ended up sitting on the floor.

“This is em.bar.ras.sing,” I murmured to myself.

So, I started downstairs.

Eventually, I reached Alice’s room.

She was spending the afternoon with my mom, so I stripped her bed and gathered dirty clothes.

When I removed one pillowcase, it slipped from my hand.

That’s when I noticed something beneath her bed.

I bent down to pick it up.

That’s when I noticed something beneath her bed.

Black fabric.

I crouched down.

At first, I assumed it was one of her school bags.

Then I reached for the strap.

Her name was still written in silver marker across the front pocket.

My hands went still.

It was Emma’s backpack.

I recognized it instantly.

Her name was still written in silver marker across the front pocket.

I sat there on the floor holding it.

Why was it hidden in Alice’s room?

Inside was a zippered pouch packed with folded pieces of paper.

Why had she told me it was missing?

For several minutes, I simply stared.

Then I opened it.

Inside was a zippered pouch packed with folded pieces of paper.

Dozens.

Some were written on lined notebook paper.

And on top were some of the angriest words I’d ever seen from my daughter.

Why did you have to do that to me? Look what you’ve made me feel!

One was written across the back of a grocery receipt.

I couldn’t understand the resentment.

The only words that escaped my mouth were, “OH GOD, NO! This can’t be real! Alice, WHAT DOES THIS EVEN MEAN?!”

For a moment, I could only stare. I didn’t even want to touch the notes.

But eventually, my grief and curiosity took over, and I searched deeper.

Deeper into the bundle of what I could only assume was hidden anger between my children.

Every single one began the same way.

Some of the notes were written on sticky notes.

One was written across the back of a grocery receipt.

Every single one had the same message on the front.

To Alice. Or, To Emma.

I unfolded the first with trembling hands.

Stop taking my socks. I know they’re mine because mine don’t smell weird.

Mom knows you ate the last brownie.

Despite everything, I laughed.

Another read:

Mom knows you ate the last brownie, by the way. I’m not taking the blame anymore.

Another:

If you tell anyone I cried during that dog movie, I’ll deny it forever.

My chest tightened.

The girls had been leaving notes for each other.

These weren’t the messages I’d feared.

The girls had been writing to each other, yes, but with love.

And judging from the dates, they’d been doing it for years.

I continued reading.

Some were silly. Some were sweet.

Fine, you can have half my money.

One mentioned a lemonade stand from when they were nine.

Fine, you can have half my money. But only because you did build the stand.

I remembered that afternoon.

Emma had sold nearly every cup while Alice decorated all the signs.

At bedtime, I had heard coins rattling between their rooms.

Then I noticed an envelope near the bottom.

Another note read:

You didn’t ruin the talent show. You got nervous. That’s different. Next year we’re doing something where nobody needs to sing.

I remembered that too.

Alice had frozen onstage.

Before any teacher could step in, Emma had walked out beside her and taken her hand.

Then I noticed an envelope near the bottom.

READ THIS IF YOU’RE STILL MAD AT ME.

Unlike the others, this one was sealed.

Across the front, Emma had written:

READ THIS IF YOU’RE STILL MAD AT ME.

I heard the front door open.

“Mom?”

Alice.

Her eyes immediately found the backpack.

I stood so quickly that the papers scattered.

She appeared in the doorway.

Her eyes immediately found the backpack.

Then the envelope.

Her expression changed completely.

“No.”

“Don’t open that!”

“Alice—”

“No!”

She hurried toward me.

“Don’t open that!”

“I wasn’t.”

“Give it to me!”

She grabbed it.

I held it toward her.

She grabbed it and pressed it tightly against her chest.

Her breathing had grown quick.

“Why was Emma’s backpack underneath your bed?”

Alice stared down.

“I don’t want to talk about it.”

“Because I took it.”

“You told me it was missing.”

“I know.”

“Why?”

Her eyes filled with tears.

“Because I took it.”

I sat down on the bed.

“We had an argument.”

“Why would you take it?”

She didn’t answer.

I waited.

Finally, she whispered, “We had an argument.”

“At Grandma’s?”

She nodded.

“What was it about?”

“It was stupid.”

“Nothing.”

“Alice.”

“It was stupid.”

She wiped at her face impatiently.

“Emma wanted to come home early. I wanted to stay.”

“Why?”

“She said she missed you. I told her she was acting like a baby.”

“I told her she’d spoil everything.”

I stayed silent.

Alice continued.

“Then she said I only wanted to stay because Grandma let me do whatever I wanted.”

“What did you tell her?”

Her face crumpled.

“I told her she’d spoil everything if she came home.”

“We said worse things too.”

I closed my eyes for a moment.

“We said worse things too.”

“Like what?”

“I don’t want to say.”

“Okay.”

She looked surprised.

“But you weren’t speaking?”

I wasn’t going to pressure her.

“We came home and pretended everything was normal around you,” she said.

“But you weren’t speaking?”

“Not really.”

I looked toward the pouch filled with notes.

“Why were all these inside Emma’s backpack?”

Alice’s mouth trembled.

“We kept them in a box at Grandma’s.”

“She put them there after we came home.”

“All of them?”

She nodded.

“We kept them in a box at Grandma’s. I saw her putting them into her bag before school started. I thought she was only trying to bother me.”

I looked at the sealed envelope in Alice’s hands.

Suddenly, everything made sense.

“She tried to give it to me.”

“Emma wrote this for you.”

Alice nodded.

“She tried to give it to me.”

“When?”

“The morning she passed away.”

My stomach turned.

“She left it beside my cereal.”

Alice stared down at the envelope.

“She left it beside my cereal.”

“What did you tell her?”

Alice started crying.

“I pushed it away.”

I moved closer.

Her voice cracked.

I wrapped my arms around her.

“I said, ‘I’ll read it whenever I feel like it.'”

She covered her face.

“Those were almost the final words I ever said to her.”

I wrapped my arms around her.

She resisted me for half a second.

Then sank against me.

Alice wouldn’t meet my eyes.

After a while, she whispered, “The counselor brought our backpacks to the hospital.”

I pulled away slightly.

Alice wouldn’t meet my eyes.

“When we left, I took Emma’s too. I hid it before you could notice.”

That explained the missing backpack.

“Why?”

“I couldn’t leave it behind.”

I picked up the letter.

She looked toward the envelope.

“And I couldn’t bring myself to read this.”

I understood.

“And you didn’t want me finding it.”

She nodded.

I picked up the letter.

For one painful second, part of me wanted to open it.

“Emma wrote it for you.”

Then I handed it back.

“It’s yours.”

Alice stared at me.

“You don’t want to know?”

“Of course I do.”

“Then why aren’t you opening it?”

“Because Emma wrote it for you.”

We spent the afternoon organizing the other notes.

Alice looked down.

“I still can’t.”

“You don’t have to.”

We spent the afternoon organizing the other notes.

Every few pages, another one brought back a memory.

The lemonade stand.

The talent show.

She held up three notes.

A Christmas when both girls had secretly bought each other the exact same bracelet.

Then Alice stopped.

“Mom.”

“What?”

She held up three notes.

Each one mentioned a tin box.

Don’t forget the tin beneath Grandma’s porch.

One read:

Don’t forget the tin beneath Grandma’s porch.

Another:

Add the blue shell.

The third read:

Do NOT tell Mom. She’ll make this weird.

I almost smiled.

That evening, we drove toward the coast.

“I have no idea what that means.”

Alice suddenly stood up.

“We have to go to Grandma’s. I completely forgot we wanted to do this last time.”

That evening, we drove toward the coast.

Mom looked confused when we arrived carrying Emma’s backpack.

The three of us were kneeling beside the porch steps.

Alice immediately asked:

“Do you have a shovel?”

Twenty minutes later, the three of us were kneeling beside the porch steps.

Alice pointed.

“There.”

Beneath the loose soil, we discovered a plastic-wrapped cookie tin.

Inside were seashells.

It was rusty around the edges.

Inside were seashells.

Friendship bracelets.

A movie ticket.

A broken dolphin keychain.

Two old photographs.

OPEN WHEN WE’RE OLD.

And another envelope.

Alice picked it up.

Across the front, Emma had written:

OPEN WHEN WE’RE OLD.

Alice laughed.

A genuine laugh.

Most of the letter contained jokes.

It surprised all three of us.

She opened it.

Most of the letter contained jokes.

I bet you’re still stealing my clothes.

I bet Mom still tells everyone about us flooding the bathroom.

Then Alice looked slightly caught off guard.

My mom covered her mouth.

She read the next part aloud.

“I know we’ll probably still argue when we’re eighty, but we should live close to each other when we’re grown up so our kids can be friends too.”

Alice’s voice faded.

My mom covered her mouth.

I reached over for Alice’s hand.

“We were supposed to have all of that.”

She stared at the letter for a long moment.

“We were supposed to have all of that.”

“I know.”

Her hand moved toward the unopened envelope inside her pocket.

She didn’t pull it out.

Not yet.

After a while, Alice took out Emma’s envelope.

That night, we sat outside beside the ocean.

The waves were loud enough that none of us needed to speak.

After a while, Alice took out Emma’s envelope.

She turned it over once.

Twice.

Then opened it.

For several moments, she said nothing.

Her eyes traveled slowly across the page.

For several moments, she said nothing.

Then she made a strange sound somewhere between laughter and tears.

“What?” I asked.

She handed the letter to me.

Emma had written:

I’m still mad too. But I don’t like when we aren’t talking. So whenever you’re finished being dramatic, come find me.

“She always understood you well.”

Alice wiped her eyes.

“She called me dramatic.”

I smiled and hugged her.

“She always understood you well.”

Alice gave me such an offended expression that, for one second, she looked exactly like herself again.

The next morning, Alice placed both letters inside the tin. Then she added a folded page of her own.

“It’s for Emma.”

“What did you write?” I asked.

She hugged the tin tightly.

“None of your business.”

“Alice,” I said, reacting to the cheeky remark.

“It’s for Emma.”

So I didn’t ask again.

Then Alice and I headed toward the beach.

We buried the tin beneath Grandma’s porch.

Then Alice and I headed toward the beach.

Halfway there, she reached over and held my hand.

She hadn’t done that willingly since she was little.

I didn’t mention it.

Alice had believed one angry sentence was the final thing that mattered between her and her sister.

I simply held on.

For weeks, Alice had believed one angry sentence was the final thing that mattered between her and her sister.

But it wasn’t.

There had been twelve years before that moment.

And now, finally, she had something else to hold onto.
