"You're Friendly Fired"

I was taking a break earler tonight and played a PS2 game with some friends. It was crazy, one of my friends who was on my team was getting kind of mad for very little reason. I can understand where he was coming from but he really needed to chill out. Friendly fire was on, which was part of the problem. The way I see it that sort of thing will likely happen in a fight in real life. Since it does, my friend just needs to chill out in my opinion. No, I wasn't trying to attack him but:

A) I was still getting the hang of the game,

B) He got in the way and I accidently hit him

Ultimately, he played and complained for most of the game about that and "double teaming." While I was thinking that he should stop crying.
