deep thoughts by jack handy me
Think of slapping a hand. If someone slaps a hand over and over again in the same spot, the slaps become progressively more painful, and the hand becomes progressively more sensitive. Once the hand is hypersensitive, its protective instincts kick in, and its main focus becomes the prevention of further injury. The person attached to the hand becomes acutely aware of any movement in the direction of the hand, of any shadow that could signal an oncoming slap.
