I pledged as a sophomore.  My best friends both went to another state school and didnt like the chapter of my sorority there.  When I joined they teased me and none of my FAMILY went to college except my two older brothers and they stayed at home and didn't join greek life.  They STILL tease me.
My brothers call it rent a friend and my parents ask me which months are worth it.  I let them think what they want but recently my mom got really interested when they came down to my school for my confirmation (I waited til I was in college although I have always been Catholic) and they saw my sisters at the church there for me.  It was really touching to her and she even offered to help me pay dues.   

 things get better when they realize who are greeks.  Tell them about famous greeks, I am not sure what GLO you are in but that is what I do. My friends accept it and only give me a hard time when I let them and my brothers know that I love my sisters, that is all that matters.

If your going to go greek, why not be a goddess?
