No, I don't make fun of them. I'm shy myself, might even have a mild case of social anxiety to be honest, so I wouldn't ever make fun of someone for something they can't really control - and trust me, you can control shyness and being socially awkward to an extent, but I've yet to find someone who has been able to overcome it completely. Besides, most guys who are shy are cute. :)
What? No! This is a silly question. Like, a persons ability to function in social situations has little o do with who they are PLUS I think it's cute... So... No. But girls are catty bitches so I can't speak for the rest of them.
