Just that really... I'm an overthinker who tends to never forget my own flaws and mistakes. And I wonder if others remember things I've done wrong when they see me and think less of me for it? To clarify I don't think this of others.
Obviously context dependant but for example - say you make a mistake at work, I feel like people only remember or focus on this despite the thousands of things you get right daily.
Or in younger days when people would embarrass themselves on a night out and it's the talk of the group chat/town/etc.
