In my job I work with children whose behaviour is challenging. They often get caught in situations where their frustration has boiled up into anger and their actions appear very deliberately designed to antagonize others. Once the emotions have blown over, I help them deal with restitution by making the comparison to housecleaning. We all make messes, and we all have to clean up after ourselves. It's not always pleasant but a job that must be done. They accept the idea that the anger was messy and it depersonalizes the event so they are not bad kids. Anger is a normal human emotion so I don't want to teach them not to be angry, but how to be angry in a way that doesn't offend or hurt others.
