Fight Bullies with Body Language

This is a good way to send a message when you witness something but don't really know the person who is doing the teasing and aren't comfortable with making a big fuss. There are several ways to send a message without even saying a word:

- Give the bully a mean stare

- Roll your eyes at the person doing the teasing

- Show your disgust and say "whatever" before turning your back to walk away

- Shake your head back and forth in a disappointing gesture

Which one of these things do you think would work best? Why?
