I've always thought that of anyone who acts like that - and I've had my encounter of a few like that - is that they're hiding something or trying to making something exist that isn't there. If you're unable to deal with another person on a regular "normal" level, that means there's something about you that's off or you're struggling to either protect or prove something that may or may not be non-existant. Everyone has their phases and whatnot of going through being a certain type of 'personality' and whatnot that probably serves the purpose for that time, so it's understandable and hell, when you're a teen, you're usually fucked up somehow someway.

If he were a real person, I would probably be able to deal with him. He's the type that I'd want to more give a hug than a slap upside the head *lol*
