Why i seem to leave games unexpectantly.

I am visiting Newfoundland at the moment, and my Xbox360 is set up in the basement where my uncle lives. And when he wants to go to sleep (11:00-1:00) i have to get off the Xbox because where he sleeps is basically right beside the television and he doesn't want to be awaken by gunfire and zombie moans.I have tried to mute the tele-vision and not talk on the mic but he says he has "no sense of privacy" when he's trying to sleep and i am 10 feet away from him.

This goes for tonight's Campaign Zombie Scenario also.

(I left the lobby at the 42:00min mark on Fire-Hazard "All In")
