It's harder in large universities I think. I remember my days at the University of Maryland, one only became "good" friends with people in the dorm. Do you commute or live there? But since classes change every semester/quarter and students are all doing their own thing in their own order, it is much harder to start and continue a good, solid relationship. Most of mine were high school friends going to the same school or roommates, etc. Just looking from the "outside" it does just look random and surface/ego/sexual.
