A 72-year-old cab driver said to me this morning: "I have to work because I need to support my baby - my 70 year-old-baby. She can't stand or walk, so she has to crawl like a baby when I'm not around." Pointing to his mouth, he chuckled, "No teeth, just like baby." It wasn't hard to detect the heavy anguish behind the light-hearted banter. "I don't know what I'll do when I turn 73. They won't let me drive anymore," he sighed and chuckled. Deep within, I could hear a silent teardrop falling.
