All of my friends pegged me as the Greek type (if there is one!) while we were still in high school. I was and always have been very active on campus and in the comunity - and that's the greek community in a nut shell!
About 20 of my high school friends came to Iowa with me - but only 3 others went greek! (2 Kappa Sigmas and 1 Gamma Phi Beta) All of us still talk and hang out quite a alot - so it's great
I have friends in DG, AGD, PiPhi, AXO, ATO, and SX at U of Illinois.
2 Friends in APhi at Easern Illinois.
Friends in Kappa and DG at Purdue.
Friends in APhi, FIJI at Indiana
A friend in Sigma Kappa and Chi Omega at Western Michigan
Another Chi O friend at U of Michigan and U of Colorado.
I know there's more

But needless to say - I have lots of greek AND non-greek friends! And I love them all the same!
