let you know, in case you don't

sometimes, it is not that we can't put on a mask, not that we can't put on a show, conceal our emotions.

sometimes, we just want to show it to you. let you know, in case you don't know.

a deliberate show of rebellion.

the kind of reaction which is not really positive, but which i fancy, because it encompasses belligerence, discipline and professionalism.

belligerence because you are fighting against him.
discipline because you don't bring it beyond an unacceptable level.
professionalism because you still do what is required.
