High school is funny. What was cool or uncool at the time can change with hindsight. I'm sure at the time these two were considered unusual, or possibly even outcasts, but I bet you everyone who went to school with them looks back and thinks, "those two were the coolest people in school." Those who march to the beat of their own drum will always win in the end, even if high school can be a struggle. As we grow older we struggle to find ourselves. Kids like these two found themselves early and weren't afraid to show off who they are.
I get the feeling that these two don't dance at prom. They mosh. Slip the DJ a twenty and ask for some The Clash. Start a circle pit. That's how punk kids have a good time at prom.
