So, let's talk about the worst gamer I ever played with on a regular basis. I'll call him Kevin.
Kevin was the guy who liked to play Druids, because they were true neutral, and that meant anything goes ... yeah, gives you an idea of who we are dealing with here.
Kevin was the guy who was playing a cleric, I don't remember of what god, but it was in a mythology where clerics of differing gods did not get along. They did not speak to each other. He encountered a cleric of another god and tried to strike up a conversation. The other fellow ignored him, so Kevin killed him ... oh ... did I mention that Kevin's character was CG? He was puzzled when he couldn't get any spells back the next day. That prompted an argument that went on for ... well ... ever. This was a common thread to gaming with him ... arguments that went on, and on, and on, and on.
More on Kevin tomorrow.
