There were several "what if" sororities for me. Stupidly, I cut a ton of sororities after first parties because I was sure I wanted to be a Pi Phi. And I'm glad I am one but I still can't believe that as a junior PNM, I just blithely cut all those groups--who knows what friends I could've made? And what if Pi Phi had cut me?
I also turned down a COB bid my sophomore year. Who knows what might have come from that?
