The next morning, I woke up to seventeen unread messages.
Fifteen of them were from Lily.
I didn't even have to open them to know what they were about.
I grabbed my phone from my nightstand and squinted at the screen.
Lily: Wake up.
Lily: Emily.
Lily: Emily Carter.
Lily: If you're dead, this is very inconvenient for me.
Lily: I need a ride.
Lily: Seriously.
Lily: Wake up.
I laughed.
Only Lily could make me laugh before I'd even gotten out of bed.
I typed back.
Me: Good morning to you too.
Three dots appeared immediately.
Lily: Finally.
Lily: I was about to file a missing person report.
Me: It's seven in the morning.
Lily: Exactly.
Me: Normal people sleep.
Lily: You're not normal people.
I stared at the message.
She wasn't wrong.
An hour later, I pulled into Lily's driveway.
Before I'd even put the car in park, her front door flew open.
Lily rushed outside carrying a backpack, a coffee, and what looked suspiciously like half a sandwich.
"You're late."
I checked the dashboard clock.
"I am literally two minutes early."
"Emotionally, you're late."
I blinked.
"What does that even mean?"
"It means I was waiting."
I shook my head.
"Get in the car."
"Gladly."
She climbed into the passenger seat.
The second the door closed, she stole my coffee.
"Hey!"
"Our coffee."
"My coffee."
"Our friendship."
I sighed.
"One day, you're going to push me too far."
"No, I won't."
The confidence in her voice made me laugh.
Because she was right.
For as long as I'd known Lily, there had never been a moment when I truly wanted her gone.
Annoying?
Absolutely.
Exhausting?
Constantly.
Replaceable?
Never.
The drive to school was filled with the usual chaos.
Lily sang along terribly to every song on the radio.
I complained.
She ignored me.
A normal Tuesday.
As we pulled into the parking lot, students were already gathering outside.
Senior year.
The words still felt strange.
For so long, graduation had seemed like something distant.
Something that happened to older students.
Now it was waiting for us.
Closer than either of us wanted to admit.
"You realize we're basically adults now?" I asked.
Lily looked horrified.
"Take that back."
"I'm serious."
"Don't say things like that before the first period."
"It's true."
She pointed at me.
"If I have to pay taxes soon, I don't want to hear about it."
I burst out laughing.
A few nearby students glanced over.
I didn't care.
I was used to people staring whenever Lily and I got together.
We had a way of turning ordinary conversations into complete nonsense.
Inside the school, the halls buzzed with energy.
Everyone seemed excited about senior year.
Or terrified.
There wasn't much in between.
As we made our way to our lockers, I noticed something familiar.
People greeted us together.
Not separately.
Together.
"Morning, Emily."
"Morning, Lily."
"Hey, you two."
"What's up, guys?"
It had been like that for years.
Somewhere along the way, we'd become a package deal.
The idea made me smile.
Until Lily suddenly stopped walking.
I nearly crashed into her.
"What?"
She pointed.
I followed her gaze.
On the wall beside the student council office hung a photo collage from previous years.
Homecoming.
Field trips.
Fundraisers.
School dances.
Hundreds of memories frozen in time.
And somehow, Lily and I were in nearly all of them.
There we were in sixth grade.
Seventh grade.
Eighth grade.
Freshman year.
Sophomore year.
Junior year.
Always side by side.
Always smiling.
Always together.
"That's kind of creepy," Lily said.
I laughed.
"A little."
"We need separate hobbies."
"We absolutely do not."
She smiled.
And for a second, neither of us looked away from the photos.
Because those pictures represented more than school events.
They represented years.
Years of friendship.
Years of memories.
Years of growing up together.
Later that afternoon, we found ourselves sitting beneath our favorite tree at the park.
The same tree we'd been sitting under since middle school.
The bark was rough.
The grass was slightly overgrown.
And someone had carved initials into the trunk years ago.
Neither of us knew who.
Not that it mattered.
This place belonged to us.
At least in our minds.
Lily tossed a pebble across the grass.
"Remember when we tried to build a treehouse?"
I groaned.
"Oh no."
"Oh yes."
"We almost died."
"We did not."
"Lily, you fell out of a tree."
"You fell out too."
"After you pushed me."
"I encouraged you."
"You shoved me."
She grinned.
"Details."
I laughed.
The memory came back instantly.
We'd been eleven.
Determined to build the greatest treehouse in history.
Three hours later, we'd accomplished absolutely nothing except getting grounded.
Classic.
"You know what's weird?" Lily asked.
"What?"
"We've known each other longer than some marriages last."
I stared at her.
"That is the least romantic thing you've ever said."
"I'm just pointing out facts."
"Please don't compare our friendship to a marriage."
"Why?"
"Because now I'm uncomfortable."
She laughed so hard she nearly dropped her drink.
And somehow, I found myself laughing too.
The way I always did.
As the afternoon stretched on, we talked about everything.
And nothing.
The future.
College applications.
Dream jobs.
Places we wanted to visit.
Things we wanted to accomplish.
The conversation drifted naturally.
Like it always did.
Until Lily grew quieter.
Not silent.
Just quieter.
I noticed immediately.
Because after all these years, I always noticed.
"What?"
She looked up.
"What?"
"Something's bothering you."
She rolled her eyes.
"You always do that."
"Do what?"
"Figure things out."
I smiled.
"That's because you're obvious."
"I am not."
"You absolutely are."
She looked away.
For a moment, neither of us spoke.
Then she sighed.
"I'm just thinking."
"About?"
"The future."
That surprised me.
Lily rarely worried about the future.
I was the overthinker.
She was the fearless one.
"The future isn't that scary."
"It kind of is."
I frowned.
That wasn't like her.
"What are you afraid of?"
She hesitated.
Long enough for me to notice.
Long enough for the answer to matter.
Then she smiled.
A quick smile.
A practiced smile.
The kind people used when they didn't want to talk about something.
"Nothing."
I didn't believe her.
Not for a second.
But I let it go.
Because everyone was allowed to keep some thoughts to themselves.
Even Lily.
That evening, I found myself sitting on the floor of my bedroom.
A large photo album rested in my lap.
Mom had brought it down from the attic.
"Thought you might want this."
Now I slowly turned the pages.
Kindergarten.
Birthday parties.
School plays.
Family picnics.
There was Lily.
Page after page.
Year after year.
Like she'd always been there.
Because she had.
One picture made me pause.
We couldn't have been older than seven.
Both of us were missing front teeth.
Both of us were covered in paint.
Both of us were smiling directly at the camera.
I laughed.
Then I turned to another page.
And another.
Until I realized something.
Most people had different best friends throughout their lives.
Elementary school.
Middle school.
High school.
Friendships changed.
People drifted apart.
But Lily had stayed.
No matter what.
And maybe that was why the idea of the future felt strange.
Because for the first time, there was no guarantee we'd always end up in the same place.
College.
Careers.
Life.
The thought settled heavily in my chest.
I didn't like it.
Not one bit.
My phone buzzed.
A text from Lily.
Lily: Important question.
Me: I'm afraid.
Lily: As you should be.
Me: What is it?
Lily: If a zombie apocalypse happens, are you saving me?
I stared at the message.
Then I laughed.
Me: Absolutely not.
Lily: Wow.
Lily: Fake friend.
Me: You'd slow me down.
Lily: I'm telling everyone.
Me: They'll agree with me.
A moment later, another message appeared.
Lily: You know I'd save you.
My smile softened.
Because beneath all the jokes and ridiculous conversations, that was the truth.
She would.
And I'd save her too.
No questions asked.
No hesitation.
That's what years of friendship did.
It built something stronger than convenience.
Stronger than circumstance.
It built trust.
The kind that couldn't be created overnight.
The kind that took years.
Years of showing up.
Years of staying.
Years of proving that no matter what happened, you weren't going anywhere.
I stared at the message for a moment before typing back.
Me: I know.
The reply came instantly.
Lily: Good.
I set my phone down.
Outside my window, the sky had begun to darken.
Another day ending.
Another memory added to the collection.
At the time, it felt ordinary.
Just another day with Lily.
Just another chapter in a friendship that had lasted most of my life.
What I didn't know was that things were already beginning to change.
Slowly.
Quietly.
Almost invisibly.
The future we'd always assumed would happen wasn't as certain as it seemed.
And somewhere ahead of us, change was waiting.
Patient.
Unavoidable.
Closer than either of us realized.
