Did you ever (warning, lots of swearing)

Did you ever find yourself in a conversation with someone who seemed nice and normal then suddenly you realized....shit this bitch is nuts?!
This happened to me. I was in a conversation with a girl and thought she was fine then she started talking about this girl I know (Who's a total batshit looney, and it's not just me that thinks so) and how they're such good friends and how well they get along.
Anyways I mention that I know her, have hung out with her and had a few times been to her apartment....see I had gotten somewhat close to this person before she revealed how emotionally unstable she was. This is a about the time in the conversation where Crazy Chick number 2 started to show her true colors. She got WAY posessive of Batshit Looney....like trying to one up me with how close they are. "Batshit and I are like kindred spirits! She's AWESOME! She's So Cool and I love her SOOOOOOO MUUUUUUUCH!" Ok I get it....glad things are working out for her.

She hadn't been over to Batshit's house (She had a really cool apartment) and for some reason was really threatened that I had...two years ago.Thats fine. The only reason I had gone to Batshit's house in the first place was because she bought my old tv and endtables and I helped her move them to her house (It was a big heavy tv) and then again to pick up some artwork she had done for a friend.
Anyways Crazy Chick kinda went nutso....I made up a lame excuse to end the conversation and later over Del Taco my GF J pretty much reinforced my suspicions. Actaully Crazy Chick is borderline stalking my GFJ....fucking crazy bitches.
