I have to say OMG to the OP. I have to say coming onto GC, saying what school you go to, your year. Then saying that your roommates are ADPi but your not interested in ADPi and then saying that you are interested in the "top tiers" and what they are and then being dropped by all but one house, hmm sucks to be you. I get being 19 but it's called maturity and having some class. You can't go onto a public forum, give as much personal information as was given, diss sororities and expect them to want to invite you back.
Word does get around, whether their are sisters from UM on these boards, there are people who know people and word will get there saying "you might want to think twice about this PNM".
I hope, if anything, to the OP, that this gave you a reality check. The phrase, "what goes around comes around" is very true.
"Sue Sylvester. Dance on Air."
"Will Schuester, I hate you."
