I'm a jerk. I have very little tolerance for drama and passive-aggressive bullshit in my circles, so if there's a problem of some kind I'll usually be sure to pull it out into the open for public humiliation via comedy - BUT ONLY IF everyone present already knows about it, AND only if doing so will bring about a more efficient resolution. Dignity is overrated.
Also, politically and morally, I hate everyone. I'm not big on the whole every-man-for-itself deal anymore, but I don't see any inherent reason to let anyone off the hook for abusing power. I don't get along much with my parents for that reason
I'm also a social gamer. I like MMOs, I love L4D, that sort of thing. In co-op play, I'll gladly help out someone who needs some tips - but I'm brutal on anyone who does things like wander off or pull too much threat: anything that wastes the rest of the group's time, really. There's nothing difficult about being competent and efficient with some regard of consideration of why everyone else is here.
