What do you lose when you stop needing to be found?

I was changing a deadbolt today, and the old one had a tiny dent where someone had been trying to pick it for years—faint, but there. I kept thinking about how much of a person’s presence lives in the things they touch, even when they’re gone. Now I’m wondering: what does it mean when no one needs to find you anymore? Not because you’re hidden, but because you’ve stopped being a problem to solve.
