I wanna go to a Sorority when i grow up?

Hi im 13 years old and i really wanna go to a sorority when i grow up. I asked my mom about what she think of a sorority. She flipped out and said they will make you do things that you don't want to do. But when i watch movies like sorority wars i really want to join one really bad. I was thinking about going to Ohio state or UCLA. I live at Illinois and wanna go to out of state but if i tell my mom i wanna join a sorority she will probably get mad at me. one more thing how do you join a sorority do you have to join a university first and get a dorm room or just join sorority. I also wanna go to zeta or delta. But all i want is friendship, trust, no drama, no gossip, or no drinking.
