D is 12. One of her female teachers always comes too close when leaning over to help with some work. Invades her personal space. Not only to my D. What should I tell her to say that will not offend or blow it out of proportion? If a colleague did this to me I'd just tell them to back off (in a jokey way) but it's different with a pupil as the teacher is in a position of power. AIBU to be worrying?
