Last month, I was at the grocery store in town. I ran into Mrs. Gable, who lived three houses down from us back when Clara was a girl. We stood by the frozen peas and talked about the weather for a bit. Then, she mentioned she had been visiting her niece out in Colorado.

“You know,” Mrs. Gable said, “I met someone who reminded me of your Clara. A music teacher.”

My heart felt like it skipped a beat. “What did she say her name was?” I asked.

Mrs. Gable smiled. “Clara. She teaches music to the kids nobody else wants to work with. The ones with learning issues or the ones who can’t afford lessons. And honestly? They adore her.”

I went home and sat in the kitchen. I didn’t turn on the television. I didn’t wash a single dish. I just sat there. I realized that while I was busy holding onto my rightness, she was busy building a life of kindness. I had been holding onto a grudge like it was a shield, but all it ever did was keep me trapped in that kitchen.

I went to the desk in the den. It is an old oak desk that belonged to my husband. I found the pen his mother gave me. It was still in the top drawer, resting on a stack of envelopes that had yellowed with time. I pulled out a fresh sheet of heavy, cream-colored paper.

My hand was shaking so bad I almost dropped the pen.

I thought about all the things I should have said forty years ago. I thought about the nights I spent staring at the ceiling, wondering if she was hungry or tired or safe. I thought about the way I chose my own pride over my own child.

I pressed the nib to the paper. I didn’t try to make excuses. I didn’t try to explain why I was so scared back then. I just wrote the truth.

“I am sorry,” I wrote.

The words looked small on the page. Too small. I wrote more. I told her about the neighbor. I told her that I heard she was doing good work. I told her that I had been wrong about the music, and about everything else.

I didn’t ask for her to come home. I didn’t ask for forgiveness. I just wanted her to know that I saw her. I wanted her to know that I finally understood what she had been trying to tell me all those years ago when she packed her bag.

I am holding the envelope now. It feels lighter than the stone I have been carrying in my chest for four decades. I don’t know if she will write back. I don’t even know if she will read it. Maybe she threw it in the trash the moment she saw my handwriting on the envelope.
