Decorum. Could we please.

Propriety of manner or conduct; grace arising from suitableness of speech and behavior to one's own character, or to the place and occasion; decency of conduct; seemliness; that which is seemly or suitable.  

I am pretty sure that coming into my kitchen, while I am cooking dinner,  dropping your drawers and asking me to see if Dad wiped your behind good enough because it doesn't feel like it, isn't it. 

If you think about the "suitable for one's own behavior", for him, it might actually be decorum.

 

The same child at dinner asked me if he could get a mohawk, because he really wants one.
