A children's book about being mean

"While it is not likely that your child will be mistreated by a wicked stepmother, monster, or bad guy, it is almost certain that he or she will be treated unkindly by a peer. When this happens, it is beneficial for your child to know how to respond appropriately. Fighting fire with fire--responding to unkind behavior by being unkind--is seldom productive. Behavior based on the Golden Rule (Treat others the way you want to be treated...) usually produces more satisfactory results." -- Page [4] cover.
