funny story. I used 2 live in dorms in London when i was in high school, and the dorm counselor would check on us every night at curfew and study hour, regular shit make sure nobody listenning to music too loud, nobody on the phone during study hall, make sure u in at the right time what not what not. Now my floor counselor always knocked twice and waited for somebody to say something before he walked in,and 2 of the 3 floors had male counselors. But my homeboy that stayed upstairs had a female one and for some reason she never knocked, so one day in study hall my homeboy comes downstairs laughing out loud and said he was beating it cuz he aint have no fucking homework and he was gonna fuck a dime 4 the first time and wanted to get tha 'quick' nut out the way, so she just storms in without knocking right when he was in full lotion on palm, hand on dick status, so he said he looked up, smiled and kept going and said "this should teach you a lesson about walking in without knocking, bet you'll knock from now one" Every since that day, she never checked his room he could stay out til whenever he damn well wanted to!!!!!!!
