Roxydiva,
I wouldn't count out AB quite yet. Especially since CDE is having so many events you can attend. You know, and we have all said, it's so important to keep your options open.
I'm not trying to be negative, just realisitic. It's awesome you liked the girls in CDE, but you only met them for a few miutes one time. And it's recruitment, they are supposed to be nice and inviting. It just sounds a little to me like it would mean a lot to you to join this group because it is the one you liked best at IU, like some sort of validation.
Do you like the girls in AB? If so, continue to give them your time. Just because you start off being known as the best friend of a member, does NOT mean you have to maintain that rep. You make a place for yourself in a house by what you give to it as an active, not your status during recruitment.
At an rate, you sound so excited, and that is great! I am sure you will end up in the perfect place for you! Good luck and keep us posted!!!
