Just wanted to add to Tink and BigV's comments about the good side of sororities and such.
There was a really nice news story on locally this weekend where a sorority had a big to do for an 8 year old kid to fulfill the needed funds for his Make a Wish. He wants to go to Disneyworld, and they raised 6000 dollars! The young lady who spoke said she thinks they had as much fun planning the party/fundraiser for the kid as the kid had being there. (Guys, don't go there)
It was quite sweet!
