My two best friends from high school went to UCF - one was a KD and the other was an AZD (she actually is not the reason I chose AZD). Also, another close friend (known her since we were 5!) went to Winthrop and was a ZTA there. A couple of girls who I was friends with through band in hs were Phi Mus at UF, and another good friend from high school was a Kappa at FSU.
Now, on to college!
I had a friend from work who became a DZ, and that didn't affect our friendship at all. There were two
Phi Mus who I became friends with, as well as another DZ, and an Alpha Chi. Also, I worked with a girl who was a ZTA at my school, and we became GREAT friends! I would joke and call her my "unofficial little sister" - she was even a bridesmaid in my wedding! Actually, my wedding party was composed of 2 ZTA's (from different schools), a KD and an AZD! If that doesn't show diversity, I don't know what does!
ETA: Oh! I almost forgot about the friend who was a Sigma Kappa at Auburn!
