ok, where to start, where to start.......
i am 7 hours away from home and i didn't know anyone when i came here, i met hte alpha gams and just loved all of them and soooooooo i joined!!! but the second my friends back home found out they were absolutly appaled that i had gone greek. now all they do is crack jokes and make fun of me and tell me i'm a sell out and that i need to buy my friends, they just assume that i am some kind of alcoholic now just beecause i'm in a sorority. they think i should just drop out and come home to my "real" friends. i have been very close with them for as long as i remember and it hurts to hear them say this crap to me. i WILL NOT quit alpha gam, i am so happy here becasue of my sisters and i would never give them up, but i don't know what to do about my friends back home, what do i tell them?? how do i convince them that i'm really happy?? they are sooooooooo dumb!!!! HELP ME!!!!!
