I watched my son get on the bus, the sun glaring badly off the windshield. I wondered briefly how his driver, Ron, never wore sunglasses. I couldn’t see Ron because of the glare, but in the 4 months that he had driven Joey to school every day, he hadn’t worn them once. As the bus pulled away, I went back to the book I was reading. I looked up a couple of minutes later, and Joey’s school bus was pulling up. … “What do you mean, John?” Ron asked, “I just got here.” My heart raced as I realized that I had sent Joey on a bus without seeing the driver, or paying attention to the bus number.
