Yesterday I heard a great line from a fellow new student that sums up pretty well the feeling of coming to a new school and not knowing many people:
(I walk past a guy I met in a class who's sitting next to another guy contentedly in a lawn chair, not saying anything, listening to the outdoor music.)
Me: Hey, we've got a class together!
Him: Yeah! It's Paul, right?
Me: Yeah- so, is this your roommate? (referring to his buddy)
(they laugh and jab each other in the ribs)
Him: Nah, we're just from the same state!
