I know a prom might seem very important when you're still in school. But after school, everything that happened or didn't happen there becomes inconsequential. The only lasting thing I have from school is a couple nerdy friends that I play chess with on occasion. The same thing is true with learning - if you want to learn something useful, go to Wikipedia instead of a school.
Don't worry. This is just biology, sociology, and psychology defending the rest of us from fascists.
Are you still mad that someone called you paki in school? And now it's every Trump supporter's fault. Please go see a psychiatrist if you still have traumas about that.
