I turned seventy-one last Tuesday. Wouldn’t you know it, same as clockwork for the past twenty years, there it was on the front doormat at six in the morning. A small wooden box. No card.

No wrapping. Just a little box with a brass winding key on the side.

I sat down on the steps and wound it up.

The tune that came out stopped me cold in the hallway. It was a lullaby. Not just any lullaby. The one my grandmother used to sing to me in her rocking chair back in 1960. I’d never heard it anywhere else. Not on a record, not on the radio. Just her voice, low and soft, rocking me to sleep at her house on Sunday afternoons. I don’t think she even knew she was humming it half the time.

And here it was, coming out of a little wooden music box on my seventy-first birthday.

I set it on the kitchen table and just stood there staring at it. My hands were shaking, honestly. Because after twenty years, I knew every track of every box that had come before. There were carols and show tunes and old movie songs. Nothing special, nothing connected to me personally. Just pretty melodies that I’d wind up once or twice and then put on the shelf in the den.

That shelf has twenty boxes now. Every year I’d ask around. I’d knock on the neighbors’ doors. I’d stop the mailman. I’d call my daughter and ask if she knew anything about it. She always laughed and said it must be a secret admirer. My son suggested I set up a camera. But I never did, because honestly, part of me liked the mystery. It was like having a little birthday fairy.

But this year was different. This lullaby was from my own history. I stood in the kitchen and felt tears coming. Nobody alive should know that tune. My grandmother died in 1972. I never had children of my own, not that she ever got to meet. I never sang it to anyone. So how could this box have that specific song?

Then I noticed something I’d never seen in twenty years. A small folded piece of paper tucked under the felt inside the lid. My heart started pounding. I actually almost didn’t open it. I guess I was scared of what it would say.

I pulled it out. The handwriting was old-fashioned, shaky but careful. It said:

“I heard her sing it too, that same night in September. She told me she’d hum it to her own babies one day. I never forgot. I remember her every birthday. I hoped you still did too.”
