Yeah, wow. Too much time. Then again I can get going on here, and on Facebook and an hour has passed when I just wanted to check messages or check for any new posts . . .
Anyhow, one thing to remember when talking about Greek letters and sororities and fraternities- Many of the sororities are actually women's fraternities. So, does that have anything to say about female and male?

Just something to think about!
I agree with wptw:
"Sororities and fraternities tend to emphasize slightly different things as ideals. Different ideals and different greek mottoes = different greek letters. Simple."
