D.K.
Acknowledge (& sometime reward) the POSITIVE behavior...helping one another, being kind to one another, etc. Talk about situations and HOW THEY COULD HAVE BEEN HANDLED DIFFERENTLY. Talk about how others perceive their actions. How do they WANT others to perceive them.....mean, bratty, rude??? What kind of behaviors are necessary to help people understand WHO they are and their personalities? Talk about situations on TV, in the store, etc. EVERY opportunity you get. They HAVE to understand how things are perceived. When you talk about somethin THEY WITNESSED, how did that come across to them? etc. etc.
