Girls you take home to mom: AOii: these girls seem down to earth and not too crazy

(I don't really know any phi mu girls so I can't really speak on them which is why they don't pop up here)
I think there are good girls and bad girls in every sorority. We have a pretty strong Panhellenic community, and I think all the sororities are great and your experience is really what you make of it. This is just what I've noticed being a part of it.
