Let's think about this shall we? Hmm, you *politely* explain to someone that they should act in a certain way or shit might happen. i.e. you might get locked out of your fucking house.

Stupid dumbass slow-learning motherfuckers might not get this.

You add to this, specific instructions on how to *not* get locked out of the house.

If the problem continues, well fuck. They are idiots.
