Actually, the last two parties I went to confirmed for me that, without knowing it, I have unwittingly stepped into a perfect little stereotypical niche by virtue of what I wear, what I do with my free time, who I do it with, who I tend to be attracted to, and what sort of little hobbies I have.
It was a little unsettling until I realized that all the people who looked like me were actually pretty cool guys who I'd probably be pretty good friends with if we'd known each other before falling into the same subculture. It's when you look around you and realize that you actually look like a lot of people you don't like, that's when you're in trouble. I figure I can accept being stereotyped by people who see me as a faceless representation of a subculture, if actually being a part of the subculture itself leads me to meet people that are interesting and friendly enough.
