Why I Don't Play Halo 3

I am sitting there yesterday afternoon working on a paper for class.  My 5 year old comes downstairs and turns on the old 360 and starts playing.  After about 5 minutes he asks me to play with him.  I decide to take a break and play.  I have never been a big fan of the game and the only reason I even still own it is the kids like to play every now and then.  I set it up and he and I start battling each other.  Before I know it, he is up 9-2.  Not only is he up, he is talking smack.  Needless to say, I quickly excused myself and returned to my homework.  Damn timmy.
