yup, it has been asked before, no biggy!
my sorority is about 150 strong. it was founded in 2003 in Tennessee. my family consists of a bunch of Zetas, a few Deltas, one AKA, and numerous Ques. my parents always saw it as "following the crowd" and allowing people to degrade you just to say you were in a group. keep in mind, my parents came thru college in the 70's, so their idea of hazing was nowhere near what happens today...
i still wanted to be part of a group, specifically because i like to do charity work, etc, and it is hard to do alone. while helping my sister do research for a paper, i ran across Sigma Beta Xi. i was surprised at the fact that it is a motherhood-based sorority. i was intrigued, so i emailed the national president, who PERSONALLY called me and had a lengthy conversation with me about the org. and invited me to come to an interest meeting. the chapter was over an hour away from where i live, but i went anyway, loved them, pledged, and crossed a month ago!
i have never been the type to be like everyone else. i dont judge those who chose d9, most went into it with the right mind and reason, while i know a few who did just because their mother was/liked the colors/thought they were pretty enough, etc. i think by considering one that isnt known/isnt "popular" you get the true effect of a sorority/fraternity. you get to be part of the beginning. i dont fade into the background...
so thats my story. hope thats what you wanted!
