DD is in her final year of high school, aged 17.
She has plenty of friends at school and several who I think consider her to be among their best friends.
However, she often says she doesn't want to stay friends with them after they graduate, they don't have much in common etc...
She's said this pretty much since she met them when she started her current school.
She also does several youth group type activities through which she meets loads of people her age, and yet she says similar things about these people.
She doesn't dislike them, she is very nice to them as far as I'm aware, she's definitely not lying about having plenty of friends at school. She just seems so indifferent towards them. She will get invited out on weekends but will almost invariably decline. She's never really had any friends who she's said she really likes or who she wants to keep in touch with.
AIBU to think this isn't normal?
