lockers

So I am really short so at school I have a bottom locker. At the beginning of the year it was great! But now the person whose locker is above me keeps dropping books on my head. By the end of the year I am going to have a concussion. Like what the hell she always says sorry but I am starting to not believe her. So I am trying to decided if I should tell her off or just suck it up. O my high school problems~To School For Cool
