A cat reaches the top of a mountain after a long climb through the snow. He is cold from the bottom of his fur to the tips of his claws. He is sodden and wet, and we all know how much a cat hates to be wet.

Once upon a time there was a man who loved to paint. He studied the art and craft of painting for many years. He chose to invest his time and energy into creating the most realistic portraits that he could paint. For him the joy came not from completing the paintings but the process of recreating the real world with the strokes of his brush.
