I used to work in an automotive factory where the bodies were welded together from sheet-metal parts. Sometimes I visited stamping plants where it seemed like every press in the plant was running and the floor shook like a drum.
Those places were LOUD!
One thing I noticed is that the people who worked there were very adept at body language. I never got interrupted, for instance, when I was pressed for time and walking across the shop. They could tell by the slight differences in my gait and facial expression that it was not a good time to stop me.
That leads me to one of my "tricks" when reviewing videos. Turn off the sound and WATCH the body language. Words lie. It is much harder to lie with body language.
Kamala Harris Puff-Piece
What I found most interesting was Harris's postures.
In the end, the motives don't matter. Harris is in the VP slot.
I would love to be wrong about all of this.
