When I pledged I got a big bro and it has been great it enables you I feel to meet alot of new people in the Greek community. When we take a lil sis we go around to the local frats and ask one of the guys to be her big bro. We usually ask which frat they would like one from. They usually love to take littles so everyone has one. They are there to listen and watch out for their little sis. I was asked myself to take a little brother. so I wsatch out for him and usually if he needs to talk i'm there for him. So my greek family is big and we all hang out together. It has made my greek life far more fun. But like it has been stated on other posts our nationals don't like this and when they come to visit the my campus where i attend school we don't wear our brother letters or anything with our sis number on it either. We do this only as a local thing and not national.
