This wasn’t, I don’t think, directed at me, but I’ll bite: Having looked inside myself, I empathize with the OP, but continue to believe that developing a social life is the responsibility of the individual, not their school.
So pretty much by definition, I’m going to argue that it’s the OP’s job to correct the problem. This is not a reflection of a lack of empathy, it’s a reflection of social realities, and the fact (yes, fact) that even at the most commuterish of commuter schools, the student body isn’t a monolithic group.
