that's a good point, still

when u r wrong, you should admit that you are wrong.

The other day I play ball with a Laozhong fellow. He just could not admit that he was wrong and lost the point. He yelled and yell, then I said, look body, you earn your point by making a shot, not by yelling at others.
also, if we don't follow the rule of game, why the hell should we play after all?
