The envelope was cream-colored and heavier than it looked.

The woman at the gate desk held it out to me with both hands, the way you’d hand someone a gift. She was young, with a neat bun and a name tag that said JESSICA.

“Someone arranged for this to be delivered to you, Mrs. Wilson,” she said. “Before you board.”

“Who?”

“I’m afraid I only have instructions to give it to you.” She smiled. “And to tell you one thing.”

“What thing?”

She glanced down at a sticky note beside her keyboard and read it out carefully, like she didn’t want to get the words wrong.

“There’s something you still don’t know about this trip.”

I stood there with my carry-on bag strapped across my chest and my brand-new passport in my hand. Behind me, a toddler was crying. Somebody’s coffee smelled burnt.

I opened the envelope.

Inside was an old letter, folded in thirds. The paper had gone soft and yellow at the edges.

I recognized the handwriting before I read a single word.

The little loops on the L’s. The way the T’s were crossed too far to the right, like the pen was in a hurry to get somewhere.

My husband’s handwriting.

My husband, who had been dead for thirty-two years.

To understand why my knees almost gave out at Gate B14, you have to know a little about me. And about Richard.

So let me go back about four months, to a Friday afternoon in June, and a sheet cake.

I was sixty-eight when I finally retired after almost forty years of teaching elementary school.

Thirty-nine years, to be exact. Most of them in third grade at Lincoln Elementary in Dayton, Ohio. Room 12, at the end of the hall by the water fountain that never worked right.

I’d kept my maiden name, Wilson, when Richard and I got married. That was a bit of a scandal back then. His mother asked me at the wedding if I was “one of those women’s libbers.” I told her I just liked my name. After nearly forty years of teaching, it didn’t matter anymore anyway. Everyone in that part of Dayton simply knew me as Mrs. Wilson. Grown men with beards stopped me at the grocery store to say, “Mrs. Wilson! You taught me cursive!”

On my last day, the kids made me a banner out of construction paper. WE WILL MISS YOU MRS WILSON. The S in MISS was backwards. I didn’t fix it.

The other teachers threw me a little party in the teachers’ lounge. There was punch in a plastic bowl and a card everybody had signed. The principal, a nice young man named Mr. Okafor, gave a speech that made me cry into a paper napkin.

Then my daughter Emma walked in carrying a sheet cake.

It had blue frosting roses around the edges, and in the middle, in big swirly letters, it said:

CONGRATULATIONS ON YOUR FREEDOM!

“Freedom?” I laughed. “I still have thirty years of laundry waiting for me.”

“Then leave it, Mom,” Emma said. She set the cake down and kissed my cheek. “Do something you’ve always wanted.”

Everyone in the lounge said “Aww.”

I smiled and cut the cake and handed out pieces on paper plates.

But on the drive home, with the banner rolled up on the passenger seat, I kept thinking about what she’d said.

Do something you’ve always wanted.

And the problem was, I couldn’t think of anything.

I’d spent so long taking care of everyone else that I’d forgotten what I wanted.
