Sometimes the kids and their subcultures should be ignored. I mean, you know, your kid is gonna be a goth or something, it happens, they're all angsty, and then they get their AA and learn drywall or something and just start drinking like you.

Or then there's the other times, when the neo-nazi gaybashing satanic evil clown rap/metal stupidocrat ultraviolence culture they're immersed in turns out to be for real.
