A while back, in real life, Manasseh's car started to slide down an icy hill toward a car stopped at the bottom (at a stop sign). Manasseh, realizing the danger, began to honk.
Though Manasseh did regain control of his car before he reached the bottom, he was flipped off for his trouble.
I wouldn't be surprised if the guy in the other car played Warcraft. Because you really do get a lot of that attitude from other players in the game.
It makes me glad that I play with reasonable human beings instead of idiots. ^_^
