Will people bother you at college?

I'm going to college in the fall. I'm 19. I'm not going to party & act like a moron. I don't go to parties or drink or do drugs. I'm just going to go to my classes & then leave. I'm not going to get involved in the activities on campus. I thought about going to the weight room, but I already have a free private gym where I live. I'm commuting. Do people bother you while you're in college? Like if I just go to my classes & don't speak to anybody, will people bother me?
