Pissed off at my roommate.
Me and the girlfriend have been having slow and unresponsive internet lately, because roommate won't stop torrenting movies all day.
When the net was last slow/unresponsive, and I asked him if he was downloading movies, he said "no". He later admitted to my girlfriend that he was, and that he lied to my face because "I shouldn't have to answer to him about whether or not I am downloading."
Actually, since we are splitting fifty-fifty on the internet each month, and since his torrenting literally brings our net to a halt a lot of the time (to the point where the browser says "no connection"), he does. And I told him that.
I also told him that next time I find out he has been lying about downloading, the next time our net is slow, I'm gonna simply reimburse his half for the month, then change the password so he gets NO internet all month. The internet is in my name, so he can get fucked.
