My highschool didn't have hs sororities, but since it was an all-girls hs, I guess you could call us one big sorority

We did have Big Sisters when we were freshman, and then when we were juniors we got Little Sisters. That was the closest thing we had. Anyhoo, I had never heard of sororities in high school until I moved down here to Galveston and they have 3 or 4 at the hs here. I think it's kind of silly, personally, to have a sorority in hs.
Funny story-I was taking a dress to get altered because I was coming back for one of Mr.ChiOJenn's formals and the lady doing the alterations was asking me what it was for, and I told her a fraternity formal. She was like, oh, what sorority are you in? Is it blah blah blah(started naming off the hs sorority names)-I was like, um NO. Do I still look like I'm in hs??

Anyhoo....
