I think that my participation after graduation (about 10 years out) has given new perspective to some of the non-greeks. They usually say things like, "Wow, I didn't know sorority members are so dedicated!" My family and friends are supportive of it, and I think most of this comes from them seeing how involved I was as an undergraduate. I've dated guys (non-greek) "don't get it" but will at least appreciate the work I do with the undergrad. members because they see the mentoring, service, etc. I have dropped guys who made fun of me because of my participation (and I've been doing that since undergrad!).
