What if I hadn't dropped out of formal rush before pref?
Out of 4 NPC sororities on campus at the time, I'd gone back to two for second round. I came out of that round interested in being part of a sisterhood, but not really feeling that either of those two sororities (or, for that matter, either of the other two) was quite the right fit for me. So I dropped out, never picking up my pref invites.
The following week, I rushed the only local sorority on campus, and found my home.
It's for the best. I have great sisters.
Plus, one of the two sororities I'd gone back to had fully half of their pledge class from my year deaffiliate before graduation.
