What’s the quietest moment you’ve ever captured?

I was at a wedding last week, and it wasn’t the kiss or the first dance. It was the grandmother standing alone by the window, staring out at the rain, her hands folded like she was praying for something she couldn’t name. No one else noticed. I didn’t even raise the camera—just stood there, breathing. That’s the kind of silence that sticks in your bones. What’s the quietest thing you’ve ever seen, really seen, without trying to fix it?
