Man, that's pretty sad. You can't just said "go make some friends" that's not how it work, some people are just bad to interact, i can relate to that even if i don't end up skipping class and bully one of my classmate.
@RaimundoBruno I think it's more along the lines of people should have friends their own age. Teachers shouldn't be their only friend(s). plus there's the professional aspect of being a teacher
