This was the reason why I chose not to go to school in-state or the "normal" JC that most of my high school went to.
We had YMCA service clubs, that lack for a better word were sororities/fraternities. I didn't get into the one that I was a "legacy" for and I decided after all the drama of the entire thing (for some reason there was just to much politicking going on where I was concerned) and did my own thing. Of course my entire high school career was a soap opera
When I did final get to ASU, the main reason I did it was because most of my classmates went to either UCLA or UCI and I didn't (and still don't) like California schools.
Most of not all the girls went greek and I believe they all stayed together from their Y club affiliations. Which is completely sad.
