And you will have to make a decision on what is more important. A real life friend or an imaginary game.
Holy Geek Social Fallacies, Batman. This is an absurd way to describe the situation.
"Friendship" is not carte blanche to act like a jerk. If I had a friend who behaved the way this guy did at the game table, I'd kick him out of the game. I'd be diplomatic about it, I'd do my best to smooth the ruffled feathers, but kicking the guy out would be my effort to preserve the friendship*. I don't hang out with jerks, so if this guy acts like a jerk at the gaming table, the only way I'm going to enjoy hanging out with him is if we're not at the gaming table. If that causes him to write me off and never speak to me again, that's his decision, not mine. He doesn't get to dictate the terms of our friendship simply by virtue of being willing to walk away from it.
Of course, we've seen nothing to indicate the guy actually is a friend of Majoru's. All available evidence is that Majoru doesn't like him, has never liked him, would be perfectly happy to never see him again, and is only prevented from reaching that happy state by the fact that they game together. (Nor is there anything wrong with this. Everybody has people they don't like.)
So what we're really talking about is Majoru's
other friends, primarily the girlfriend. If Majoru kicks the jerk to the curb, these other friends may decide that Majoru isn't their friend any more. To which I reply: If they really would do that, then
they are the ones putting an imaginary game ahead of a real-life friend, and they are crappy friends. Lose 'em and start looking for friends whose social skills have advanced beyond junior high school. On the other hand, it may turn out that they're better friends than Majoru is giving them credit for, and won't cut him off just because he shows a little spine. In that case, what's to lose?
[SIZE=-2]*Assuming I
wanted to preserve the friendship. A guy who runs off and leaves his buddy and girlfriend stranded, over "an imaginary game," is going to need some pretty stellar qualities to justify keeping him around. But we'll say for the sake of argument that the guy is one of those people for whom D&D acts like a
helm of opposite alignment.[/SIZE]
