The pathological liar thread for some reason reminded me of this guy I know with seemingly two personalities and thought I'd make a thread on people like this. A guy I met last year was one of the nicest and friendliest people I've met. Dude was smiled a lot, spoke very properly (never cussed or used slang) and sweet to the point I thought he was gay. I wasn't close to him but I always thought positively of him. Then one day I run into him at night at a bar and dude grabs me and starts talking about how he's gonna get pussy. It surprised me because I never seen him speak like that and he was really aggressive about how he had to tell me that he was getting laid. I just assumed he was drunk and brushed it off, but every time I ran into him at night after that, I saw him getting drunk and for some reason talking shit to women and making them cry. Even when he wasn't talking shit, I just found him to be an unpleasant person to be around. Every time I saw him during the day, he was back to being super friendly and warm. Total switch in personality. The last time I saw him he was trying to piggyback off me and my friend while we were trying to talk to girls. He would get pissy at me for not introducing him to girls and criticized my game the whole time when I and the other guy were the ones actually approaching them. And he wasn't even invited to hang out with us but ran into me and decided that he was going to tag along. Probably the most drastic disparity in personality I've dealt with. I don't contact him and I'm sure if I hung around him long enough, I'd get in a fight. The worst person I've heard about is my current girlfriend's mother, whom I've never met (she died long before I met my girlfriend). The woman had legit psychological issues and my girl has some batshit crazy stories about her.
