First off, Mom is A Real Trip, well amybe over protective to say the least.
This Girl is going to have to make up Her own mind at some point in time.
Maybe, Mom from Hell doesnt realize the benefits that Her Daughter can learn from being in a Sorority.
Can You talk to Mom and explain or is that a No No?
I also figure Mom want a Greek or wouldnt even be asking so many questions. Also, who is paying Girl or Mom? Might have an impact.
Basically, this NM is going to have to make up HER mind one way or the other!
