Since this was posted, I'm proud to say that 2 of my daughters--1 Chi O and 1 AOII--are also Order of Omega members! If they can't be my sisters in Pi Phi, at least we can share Order of Omega!
Also, I made an idiot of myself tonight re: OOO. Several teachers and I were in conference with some parents and I caught sight of a certificate with a giant Omega on it about 20 feet behind the teacher whose room it was. I exclaimed, "Hey, you're in Order of Omega!" (Weird looks from everyone else--they were all talking about some student.)
She's an Alpha Gam from Tarleton State!
