Some poeple are not social. You don't get into uni/college etc ba<x>sed of social skills! Thank god for me. You can't make someone social. They are or they are not, maybe they will meet someone one day and become social. Don't force others into unconfortable situations and accept that you have unsocial classmates.
The only issue I see, is a grown a$$ man who can't handle a simple little situation like this on his own, I think you're 1-5 ,not 31-35
Did you not visit the campus first?
Dream school? Seems like the only option rather than the dream option. Why care about if they are social or not? You're there to learn, not hang out.
