Why so serious?

      Have you ever been in a room with a group of guys playing Call of Duty on an Xbox? If so then I'm sure you can relate to this. At first everyone is all excited and all pumped up to play the game then, BAM! It happens. Someone screen cheats. It comes out of nowhere, one minute everyone is laughing and joking and the next comes cussing and death threats. Someone's mom is insulted, tempers flare, and egos rage. Don't let me get started on the angry rage mode insults because of someone killed someone too much..ON A FREAKING GAME THAT THE WHOLE GOAL IS TO KILL PEOPLE! I don't get it. Then minutes later it's like nothing ever happened. Everyone is best buds again. I guess it's a guy thing. Girls would totally lose friendships over that. Full blown fights would break out and a death may occur. So tell me, WHY SO SERIOUS?! After all it's just a game.. isn't it?
