What’s the last thing you lost that you didn’t miss until it was gone?

Just found a spare key in my coat pocket—had no idea it was missing. It wasn’t even a special key, just one of those generic ones from a rental place years ago. But I felt weirdly relieved to have it back, like I’d been carrying an absence without knowing. Now I’m wondering: what small thing did you lose that only made sense after it vanished?
