ASPD?

A recent reminder:

I'm quite aware that smiling makes people receptive to information - I also generally don't care for people who don't make themselves receptive to information.

So, as I'm not naturally smiley on most trivial matters (business in general), I save energy by not smiling, and prefer to let nature take its course with people who don't pay attention to what I'm saying.

That describes my anti-social preferences quite well - so maybe I am an introvert after all. But I so maintain that it's mainly for the want of adept conversants.
