I have had some apologise to me.
The first was a Missisippi River diver, he's in murky, muddy atmospheres where vision is very limited yet all kinds of metallic trash and who knows what await him.
Like those legendary monster catfish that lay around the river dams just eating what comes via the current .
The second was actually a group , the Hillbilly Family from hell!
"Ma' had no teeth, wrinkled old woman, drunk, scared needing someone's arm to hang on to one of her almost adulterer kids or me, my arm! "Ouch!" (She has fingernails!) I pull away from her and put some distance between us quickly, then she begins snagging her kid's arms!
These people seemed normally fearless. Flashing red lights and a siren behind them and gunshots following wouldn't have made them even consider finding fear and they would be ignoring the speedometer telling it's lies about a 120-something per whatever?
Then there was the soldier. He was from West Germany and had been in their army, then he joined our United States Army. He was the guy who told me he had been in a much scarier house, the mock battle house where a trap door drops you down into the basement onto a concrete floor! ("Now go play your war games with a broken ankle!")
I guess you wouldn't want a bunch of "Woosies" in Your army!
Some of the other unscarables had no imagination to prod their brain toward fear, or is it to allow their brain to feel it?
Like the guy who always finds fun by passing on hills where they paint those double yellow lines.....no imagination.
