Listen to amy. You don't want to have to change to fit in with a fraternity or sorority. The reason I chose DU was because they acted genuine during rush -- not fake. They showed interest in me and I could see myself fitting in, and I made the right choice. If your school is not a big greek school and you don't have a lot of choices, just look anyway and see where you fit in. Act like you always do, because there is nothing worse than faking during rush, then finding out you joined a fraternity that gave you a bid only because you were acting like a jackass
