What a punk!
My mom used to play games, from the NES to Xbox, with me all of the time so we had that extra level of bonding. The only times we argued over a game was when she owned me on a couple games after I taught her how to play. Now I won't play any of the SSX games and Mortal Kombat games with her because she's "too L33T for me" - in her own words.
This kid needs to be put in his place.
