Which aspects do you think makes a person unique?
I normally do NOT engage in conversation because each soul has a story and lots of opinions.
So what I look for are the “feelings” of the person by the look off their eyeballs and overall demeanor.
I could see if the person is “shifty”, uninterested, irritated, or joking. But for the most part, I also consider mannerism as a vital aspect of one’s demeanor.
It’s more than an observation but of a “sense” of something is off or if the person is hiding something.
