I remember going to his house a couple times for after parties.  The first time he cornered me and told me he doesn't like takers.  If I was gonna be there, I needed to give back.    Another time i was going pee with the door closed and he came in without knocking and blocked my exit.  He told me that I was breaking the rules. The hair on the back of my neck stood straight up.  I went outside with the excuse of smoking and waited outthere for about an hour when my friends finally were ready to leave.
