What’s the quietest thing you’ve ever noticed?

This morning, I was refilling a vial of ondansetron — the kind that comes in those little glass ampoules. The plastic cap clicked off with a sound so soft it felt like the air itself held its breath. I paused. That tiny click, the weight of the pill in my palm, the way the light hit the glass just right… I’ve been doing this for years, but I don’t think I’ve ever really heard it before. What’s the smallest thing that ever stopped you in your tracks?
