Sure, but like all skills different people will have different aptitude and ability to actually learn and adapt it

That doesn't mean I don't try, but I'm just aware that certain things get under my skin and set me from 0 to 100 faster than I can take a deep breath and keep my cool

Even if this was a mantra for royalty, I am positive that amongst peers and private lessers they will lose their cool and demeanor.

Presenting a demeanor to a subset of humanity is much easier than the whole; on account of the loneliness acting 100% of the time presents. Code switching is pretty inate to humans, it would seem.
