Because there, folded impossibly small in the hollow behind the works, was a scrap of paper and a tiny photograph, and my breath left me all at once.
The photograph was of me. A baby, held in the arms of a young man I barely recognized as my father, both of us laughing, his whole hard face open in a way I had never once seen it in life.
And on the scrap of paper, in his cramped hand, worn nearly to nothing from riding against the works for years, were a few words.
My boy, it said, I was never good at saying it, so I kept it here, against the ticking, close to me every day, the way you always were, even when I could not find the words to tell you so.
My father was a hard man. Quiet. Sparing with anything soft. On his deathbed he pressed this watch into my hand and could not speak, and I took his silence, the way I always had, for a man who did not know how to love out loud.
He knew. He had carried it on his own wrist for years, wound against his own pulse, a photograph of the son he could not embrace and the words he could not say, ticking away next to his heart every single day.
I lowered myself into my chair and I wept, thirty-one years too late to tell him I understood.
All that time I thought the watch was the only thing he left me. It was not. He left me himself, folded small behind the works, the whole tender heart he kept hidden behind a hard face his entire life.
I have not put the photograph back. It sits on my desk now, in a little frame, a young father laughing with his baby son, the way he never let the world see.
I understand the silences now. The way he would set his hand on my shoulder and then take it away too fast, as if warmth were a thing he had not been given enough of to know how to give. He was not cold. He was a man who never learned the words, and so he found another way to hold his son close, one tick of a watch at a time.
I have grandchildren of my own now, and I have made myself a promise. They will never wonder whether I love them. I say it out loud, every time, the words my father could not, because he taught me, in the end, exactly what it costs to leave them unsaid.
But I still wear the watch, every day, wound every morning against my own pulse now. And I know, at last, what it was always carrying. Not the hour. My father love, kept close, waiting patiently for the day his boy would finally hear him say it.
I hear you, Dad. I always hoped. Now I know.
