Well, here's the latest update on my saga...
I found out I can't pledge the NPC sorority. Since I'm not a full-time student and never will be, I'm ineligible, thank you and goodbye.
I never ended up making that call or writing that email yesterday, I just didn't show up to the pledge activity. I'm guessing that they know now I am de-pledging, but I still have to make it official.
I can't tell you all how disappointed I am not to be able to become a part of greek life. It's something I've always wanted to do since I was a little girl. Thanks for all of your advice, though..... I'm sure you'll see me lurking around here still
