My mom does. I am 14, but my mom lets me play rated M games. My dad only lets me play E and T games. He gets all hyped up and takes a game that is rated M from me and plays it for himself.
Even when I was little, as long as I skipped the sex scenes for GTA and didn't get one of those games that were way too gory, I was fine. xP My little sister was the only one that needed permission from me, she got hooked to using peach on super smash bro's melee. o.O
