Reminds me of the time my mother was standing outside of our village shop to have a chat with the local GP who lived down the road. She (the GP) had her son with her and he was asking repeatedly if they could go back into the shop so that he could have an ice cream. The answer was a repeated "No" so while the woman carried on talking to my mum, the son reached up and bit her really hard on the arm. She didn`t bat an eyelid! Completely ignored him - my mum was aghast. The kid went on to be excluded from school for pushing a boy down the stairs, causing a broken leg. So much for ignoring bad behaviour!
