I, without a doubt, am majoring in sorority. I kind of can't figure out how you wouldn't. I mean, you live there (for those with Houses) and almost every aspect of everything you do envolves some part of your org. My mom still doesn't understand the whole Greek thing, and she still calls it "E K" rather that Sigma Kappa. To me, it's a part of who I am, and I don't understand why some people aren't as enthusiastic about being Greek as we are.
In my house, we have a name for people like me: Super Sigma's. They are the ones who are all about the house, and getting envolved and making sure other people are getting involved. We live and breathe Sigma Kappa. I probably know more about my Org and greek life in general than anyone else I live with, and most people I meet on my campus because I just love it that much.
When I was an Alumnae, I helped re-colonize a defunct alum chapter, and did as much as I could to help my chapter. I know that when I when I become an Alum again, I'll do even more because I have a better understanding of how things work and how I can help. And I hope that I can find a guy who, at the very least is Greek, just so he understands my obsession.
