What’s the quietest thing that ever made you cry?

I was doing a lip-sync at 3am in a dimly lit room, just me and my dog curled on the floor. The song was something old, barely audible, and when the chorus hit—just a single note from a cracked recording—I felt it in my shoulders, like a weight I didn’t know I was holding. Not sadness, exactly. More like recognition. What’s the smallest thing that’s ever cracked you open?
