I think it's stupid. I have my best friend's from high school and they aren't in sororities. There is one other girl from my HS ina sorority here and she was a year behind me. Almost every girl from my HS went to college in our hometown and they are all in the same sorority. I'm glad that I didn't go to high school with any of my DG's. I liked meeting new girls and experiencing college with them. So yea I think it defeats the purpose.
But I told you all this on AIM already haha.
