Twin related question???

Ok I have an identical twin sister, we basically go everywhere together (we kinda have to considering we share a car) and do just about everything together...this year we have all the same cles together, every single, one! Its fine I guess since we commute and its easier for our schedule, but next year will be livin on campus and we'll be sharing a dorm, which is ok too cause im not ready to share living quarters with a stranger, but i DO want different cles and not to sound mean, but i want my own friends, i dont want my friends to talk her and i dont want her to talk to my friends, i want my own space while we're outside of dorm....what should i do without being to mean?
