When someone hears that I train in mixed martial arts:
"Do you have a black belt?" "Have you gotten into any fights?" "Can you break bricks with a karate chop?" It's not so much the questions themselves but the disappointed looks on their faces when I say "No." No, not everyone who trains in martial arts is some kind of invincible grandmaster champion who can knock out an army while wearing a blindfold.
When a group of people is having a conversation about a topic I know nothing about, or am not interested in:
"Why aren't you saying anything?" Hmm, I don't know. Maybe it's because I have nothing useful/interesting to add to the group's conversation about some party that I wasn't invited to, some movie I couldn't care less about, or something else that I know absolutely nothing about, and no one is making any attempt to include me in the conversation?
Or maybe it's because when I actually do have something to say, everyone just gives me a blank look or outright ignores me?
"You don't go out to clubs? So you just stay at home all the time?" Yes, of course, because there are no other hobbies that involve social interaction besides going to bars/clubs. Fuck, I hate the stereotypical college mentality that getting in some drunk chick's pants is the only thing worth living for.
