Heh, ahh yes....this looks familiar. We've gotten this PLENTY when word got round that we were starting a new sorority. This won't be the end of it, so grow some thick skin and go with the flow. It'l be hard to ignore it, but you just have to prove yourself to them. Anyway, she sounded like a big ole b*tch, looks like you're not missing much.
Remember, to the other sororities, you're COMPETITION!!
PM if you want hon, good luck
