The Greek scene at my school is weak, so I never seriously considered pledging. Plus, I had a great group of friends so what did I need a fraternity for? But the Greeks do seem to have a lot of fun. My friends are just not as into bar-hopping and partying as I am, and if they want to "chill out" during a weekend, my hopes for a crazy weekend are pretty much shot. I have a couple of good friends who are partiers, but they are both Greeks and thus usually busy with their frats.
I'm a rising junior so any chance for me to pledge is over. I don't really regret not doing it, I suppose, since the Greek scene tends to attract a lot of douchey people. But still, I would REALLY like to find some guys that I can rely on to be up for a wild weekend. Sigh.
