It's weird because when I see a young lady of another organization I just simply say,"hello fellow greek sister." i hardly see people wearing their paraphanelia in NY so when I do, I make it known that I am a member of SGRho and have pleasant-but brief convo. As far as me greeting one of my sorors...i go all out: I give them an EEE-YYIIPP, a hug and very rarely, the grip.
