Ok I've got this group of school friends and when we were 25 a few years ago - one of them was still obsessed with impressing the popular boys in the class even though we left school 10 years before. We were in a nightclub one Saturday evening and she spotted a lad from our school - turned to me and asked something like "tell Mark that Sarah is keen to talk to him" - something very much along those lines. I did go up to Mark but instead of mentioning Sarah had a straightforward sensible conversation with him. A few months later I left this group because there was this vibe throughout the group.
AIBU to have found this immature and left the group?
