I was walking past several parks today. People were out with their dogs, always in the shade, playing.

One shaggy-haired young man looked like he was in his mid-twenties. His canine companion looked old and out of shape. The guy lightly throw a Frisbee. The dog galloped after it. After twenty feet, the dog stopped and turned around, looking for the disc. It sailed over his head and landed four or five feet behind him.

“Behind you,” the man called to the dog. Turning around, the dog saw the Frisbee. Picking it up in his jaws, he trotted back, but stopped four feet away and settled down in green shade.

“Drink water,” the guy said.

The dog went to a water bowl and took a few sloppy laps. “Bring me the toy,” the man said.

Doing as told, the dog brought it over and put it on his man’s feet.

“Ready?” the man asked.

Watching him, the dog began jogging away. The Frisbee was launched. The dog ran out, stopped, and turned around as the Frisbee landed behind him.
