I once had the privilege of observing the following:
Blue haired little old lady in a Cadillac cruising the supermarket parking lot recognizes old geezer in a Mercedes coming the other way down the aisle. LOL and geezer stop, drivers window to drivers window for a confab. Twenty-something in a small pick-up passes LOL on her right and parks in parking space hard by the store entrance, enters store. I park and enter store.
As I am shopping, the LOL finds the pick-up driver in the same aisle I am in and confronts him. The LOL launches a scathing attack on the pick-up driver for taking "her" parking space.
The pick-up driver, when he finally got a word in, calmly and quietly (so that the LOL had to concentrate to hear) began a Socratic dialog:
P/U driver: "Do you know who I am?"
Little Old Lady: "No."
"Do you know anything about me beyond what you have seen and heard tonight?"
"No."
"Let me tell you about my self.
I am NOT a hair trigger psychopath, though you dont know that.
Because I am not a psychopath, I am not going to follow you home to murder you in your bed tonight. But you dont know that.
Because I am not a psychopath, I am not going to follow you home and rig your toilet so that the next person to flush it dies of chlorine poisoning. But you dont know that.
Because I am not a psychopath, I am not going to follow you home and burn your house to the ground with you in it. But you dont know that.
Because I am not a psychopath, I am not going to do any of the dozens of very nasty things to you that a psychopath might. But you dont know that.
Now dont you think that, given how little you know about me, that you might be a little more polite?"
The Little Old Lady lost control of her bladder.
In my younger days, I stored that dialog to use as my own, should the opportunity arise. Now I realize that, of course, it works both ways: the pick-up driver had no idea of what the LOL might be capable of or do.
