A memory from childhood, of an adult enjoying my pain...

I just remembered this suddenly out of nowhere...

I remember being a young teenager, I was competing in field and track. While running, I knocked into another girl and she fell, scraped and hurt her knee bad and there was blood on the running track. I stopped running and walked out of the track in a kind of shock, I found a secluded place and sat down and just started crying. Then after a while I look up and am startled, and there is an adult man there. And he walks past me looking down, with this... disgusting smirk. I feel absolutely disgusting thinking about this, and so angry now as an adult remembering this. It was this disgusting, smug, superior narcissistic evil smile. I remember being shocked at why an adult was smiling when I was crying, instead of looking sad and comforting me, it was the day a huge part of my innocence died I think. And I am just so angry, thinking about what kind of a man this is who behaves like this. I wish I could go back in time and smack this disgusting man. Today I know well what type of man this is, I met a lot of them later and they all have that same disgusting smile.
