I am old enough to have known some people who have actually lived through a runaway horse adventure. Not too long ago, in the way I figure time, people's main mode of transportation was THE HORSE.
The horse is a large square animal with a leg at each corner, and you got from place to place by sitting on his back... sitting right down on the horse.. and saying GITTYAP.
You steered the horse with reins. Some reins ran to a bit in the horse's mouth. He didn't care much for the bit, who would? You tugged on his mouth to make him whoa (stop).
Sometimes, the family horse, Fred, or Bessie, or Dobbin or Nellie would become agitated, and TAKE THE BIT IN HIS TEETH (so you couldn't tug on his mouth) and take off for Cleveland at a dead run. There you were: completely helpless, on a horse that wouldn't pay attention to your tugging or your yelling or your tears. Where Nellie wanted to go, you went. And fast. You couldn't bail out, Nellie was going full speed. You hung on.
What am I getting at? Just this.
My Hewlett-Packard sometimes takes the bit in his (her) teeth and runs. Tugging at the reins, that is... clicking on the red x in the corner of the window... doesn't stop him. Sometimes turning off the computer at the console doesn't stop him. I have had to UNPLUG THE COMPUTER FROM THE WALL. That is equivalent to knocking Nellie unconscious with a club.
So, what would you do with a horse that ran away with you? When you finally somehow got control, you gingerly urged him home or shopping, or visiting, with kind words and nice slow, soft guidance. So I do with my computer.
And if your horse ran away with you two or three times a day, you would take him to an expert for retraining. There are such specialists for computers too. But if that failed and he continued to run... you'd SELL him. And if you couldn't sell him, or even give him away (there is little market for used computers) you would take him to the GLUE factory. (That is a gentle metaphor that means you'd put him down... which means KILL him.)
A horse that runs away is useless. So is a computer.
I hope my Hewlet-Packard has been listening to this.
