That's an interesting question. Maybe all politeness is fake to some degree (you're interfacing with someone by being nice regardless of what that person does)

That's an interesting question. Maybe all politeness is fake to some degree (you're interfacing with someone by being nice regardless of what that person does), but we say "fake politeness" when you're spending a lot of energy to keep the politeness filter on. Tell me if you have a theory about real vs fake politeness.
