If your a real poker player(ie. addict) you will learn that, like everything else, you take the good with the bad. Its impossible not to get mad over a bad beat, but its all about how you express it. Mathias Anderson for example i believe has no place around a poker table until he grows up a little. Poker isn't a sport like football where you yell at each other and make a scene. Its a gentlemans game like fencing, you have equal respect for everyone around you regardless of how well they play the game. You can drop that respect as soon as you see they don't deserve it, but making a scene in my opinion has no excuse. And if your rockets lose to a 23 off, just sit down and accept it and make a comment like "nice hand". Everyone knows you were just part of a bad beat, there is no reason to carry on and try to prove a point that is obvious.

And you get more numb to bad beats that the years roll on. You learn that you won your fair share of bad beats but you have also lost your share(or more than your share as it will always seem). But you know what? IT WILL HAPPEN AGAIN!

Suck it up, sit down, and play.
