Congrats! Though I am glad that you've reflected a bit and realized that you maybe wrote some others off for the wrong reasons. I do find it ironic that sometimes PNMs say that a sorority had a weird/odd mix of girls, because I think they tend to think of one sorority as the "______" sorority (fill in the blank with whatever: blond, religious, scholarly, etc), yet once they actually become familiar with the Greek system, they realize that diversity in a sorority is one of the best things.
But congratulations! I hope you're very happy there!!!
