I love taking walks through our park. Today, as I passed by the tennis courts, a woman was walking to her car, tennis bag in hand and a dog in tow, off his leash. She arrived at her car long before her golden retriever. He was old and arthritic with an awkward gait. She called to him kindly and he walked to her slowly, at a speed he could manage. He couldn't go any faster, and she didn't expect him to. She didn't complain, and neither did he. He was giving her all he could, and she didn't expect any more than he could give.
