imagine the kid goes up to person A and they're like "mom/dad, im having problems with this kid at school"
and person A says "deck em in the face"
and their kid is like "okay"
the next day person A and B are called to the school because their kid punched someone
person B turns to their kid while person A nervously sweats and B is like "sweetie, why'd you punch that kid" and their kid is like "mom/dad said I could do it if they were bothering me"
and person B turns to A with this angry look
