Well let me say this with risking ticking off a bunch of people about my real hatred for the greek system. I have probably way more negative experiences involving that than I do positive. I have some good friends that were greeks, also lost some friends that became greek and turned into complete jerks, also met a lot of these same people that treated you like you weren't worthy to be in their presence once they found out you weren't greek too. Probably one of them most uncomfortable moments of my college days was when my sororiety girlfriend took me on their "house party trip" or whatever it was with their greek brother house. Went about an hour out of Ames on a bus to some bar they had reserved for the night. Once I started meeting people and they found out I was not a frat boy like most of the guys on the bus were all the sudden I was either looked at differently or not worthy of socializing with some of them. Very ackward night and some of the very same stereotypes these people try to say don't exsist they didn't do a great job of exhibiting behavior that would make me think those stereotypes are untrue.
Sorry, probably already said too much but eventually the sororiety girl drama came out and that relationship because miserable toward the end and I had to get out while I still had some kind of sanity. Although I do have a funny story of how one of the gay guys on the floor I lived on purposely joined a frat hoping that would "get the gay out of him" and ironically all it did was one of his house brothers wound up pinning him down on the floor one night and seducing him! He said he was completely shocked and was the last thing he thought would have happened to him there!
