Funny story. I did this back in high school. This one girl I was really cool with started throwing hints at me (and i missed almost all of them) kept trying to ask me over and eventually I was like ok sure. Her myspace was just pictures and I didn't really talk to her other than in school and she kept it all about me. So I asked some people and found a guy who was cool with one of my friends went with her so as awkward as it was I asked "sooo..you went with (not saying name just in case she's on here)" and he goes "DUDE SHE IS A PSYCHO, DONT EVER GO OVER HER HOUSE DUDE". I'm now freaked out because I'm bout to head over there on the weekend and he tells me how she really is bipolar and no matter what she will flip out and try and stab you out of the blue just because. Enough said, I told her I got something came up and she threw a book and the desk at me because of that. Yea you would think witnesses right...nope, she didn't care. Long story short she got expelled, I dodged a bullet and maybe more just by doing that. TL;DR crazy chick liked me enough to want to kill me in school and the info from a ex saved me from worse.
