Told our kids that if somebody is bullying them and they don't stop when asked, to bust them in the mouth. My boy is timid and would never do it. Daughter (8 years old) on the other hand is kind of a souped up wildcat. Her fear is 'getting in trouble and in school suspension'. I told her big deal, you'll have to go sit in the principals office (her buddy) and read books all day (not a punishment for her). She's still hesitant though. Even tried to sweeten the deal with promises of ice cream afterwards. Time will tell.
