I have a different perspective about the no hugging/hugging rule (question). I pledged and am active in a LGLO. When I went to Rush week eventhough I hardly knew any of the actives, we were all hugged or shoke hands with them. I wasn't freaked out about it , I guess it's just a part of our culture to hug and kiss each other on the cheek everytime we see each other. Even our non-Hispanic members, i.e. White and Black, do it now.
Everytime us sisters see each other whether in private or on our way to classes we always stop and hug/kiss each other and most of the time we get "THOSE" kind of looks from GDI's and other Greeks. So having a no touching rule for my sorority would really be hard.
