It's funny my parents (a Tri-Delt and a PKA) both hated that I was Greek in college because they thought it pulled me away from my studies. Which it didn't, I was just slack for a while by my own choice. ANYWAY, they love that I'm involved now as an alum. It's so funny too, but it's like the realize there's no studying that needs to be done and that I already have my job, so they're all about it.
My other friends up here are either in their own AA's or just haven't heard me talk about my own, but pretty much all my friends happen to be Greek (by chance), so I don't think any of them would care.
