I believe that misbehaviour is often a cry for attention, however I do not believe in rewarding it.

At the time of the person's misbehaviour, I'd be a hard ass, not allowing the behaviour to continue, and making it clear that inappropriate behaviour will not result in warm fuzzy happiness for the perpetrator.

However, when I start to see goo behaviour (or in extreme cases, even an absence of bad behaviour) that person will get my positive attention and I will attempt to give that person what they need.

Funnily enough, the person I do this with most is my Mother! LOL
