I got bullied from time to time. Once I called my mother in, and she and the teacher talked it over. The teacher said, ""Why a big boy like you could wipe the floor with those bullies."" That's what she said. I did later pound one of the bullies--but I didn't like it much more than being bullied. On another occasion, I tried being a bully for about five minutes--that felt really unpleasant. Mostly I avoided situations. Developing a scary insane smile is useful. Also yodeling and howling while smiling insanely and advancing may work.
