I have a son in his third year and a daughter in her first year and both have commented on the number of kids who seem to do this now. People go to the same University as a group of their friends, form a bit of a clique and are not really interested in friendships outside that circle.
DD in particular has found that most of the girls in her flat seem to have come with close friends already in place, and though she gets on fine with them, goes on nights out and socialises, no one is really interested in making new friends. They do include her in their groups from home but she feels a bit out of the loop.
I have told her not to fret; it's early days for finding bosom buddies and she's a nice friendly person who will find her people. But just wondering, has anyone else's offspring encountered this? Is sticking with your school mates a thing now? I don't think it is really what University should be about.
