Men do change, and change comes like a little wind that ruffles the curtains at dawn, and it comes like the stealthy perfume of wildflowers hidden in the grass. Change may be announced by a small ache, so that you think you're catching cold. Or you may feel a faint disgust for something you loved yesterday. It may even take the form of a hunger that peanuts won't satisfy. Isn't overeating said to be one of the strongest symptoms of discontent. And isn't discontent the lever of change?
