That cartoon pretty well captures it. Unfortunately, there are people who are permitted to grow up thinking that they can manipulate people by just being insufferably obnoxious, demanding and abusive. Most people will just give them what they want to be rid of them, but for the sake of their future victims, it’s better not to give in to them and thereby reinforce and enable their anti-social behavior. It’s really the job of mothers to nip that kind of stuff in the bud.
