Authoritarians are the easiest people to get along with. All you have to do is just ONE THING. OBEY them. That's it. Piece of cake right?

You obeyed your parents in all things and you got along with them didn't you? Well just think of the authoritarian as a parent. Don't cross him/her. Obey. You've grown up doing that so you don't even have to learn a new trick. Just stay your child self.
