AITA I'm in high school and there's a group of my friends, there's about 6 of us. There's this one guy who is in the group and no one really likes him, but he has no other friends. Nobody really minded him being there until one day he decided to follow one of the girls in the group home. That happened a couple months ago and now he has began staring at one of the other girls in class. I decided to confront him about it and I called him a creep. Should I apologise and if not, what should I do? Because nobody in the group wants him there and he's forcing himself into the group.
