After 20 years as a full-time wife and mother, I decided to be a school bus driver for I loved kids. After hard practice, by the time school started that year I'd gotten the hang of it. I was happy in my new work. I became a combination of chauffeur, nurse and friend. And if the kids needed it, I'd put on my "Tough Big Sister" act. It was a lot like my previous job---being a mom. When I think about my years of bus driving, many things crowded in, but mostly, I remember Charlie. Charlie, eight years old, with blond hair and crystalline gray eyes, began riding my bus in September of my fourth year driving. They all had stories to tell me about their summers. Charlie, though, ignored me. He didn't even answer when I asked his name. From that day on, Charlie was a trial. If a fight broke out I didn't have to turn my head to know who had started it. If someone was throwing spitballs I could guess the culprit's name. If a girl was crying, chances were Charlie had pulled her hair. No matter how I spoke to him, gently or firmly, he wouldn't say a word. He'd just stare at me with those big gray eyes of his. I asked around some, and found out Charlie's father was dead and he didn't live with his mother. He deserves my patience, I thought. So I practiced every bit of patience I could muster. To my cheery "Good Morning", he was silent. When I wished him a happy Halloween, he sneered. Many, many times I asked God how I could reach Charlie. "I'm at my wit's end." I'd say. Still I was sure that this child needed to feel some warmth from me. So, when he'd pass by, I'd ruffle his hair or pat him on the arm. Toward the end of that year, the kids on my bus gave me a small trophy inscribed "To the Best Bus Driver Ever". I propped it up on the dashboard. On top I hung a small tin heart that a little girl had given me. In red paint she had written, "I love Polly and Polly loves me." On the next-to-last day of school I was delayed a few minutes talking to the principal. When I got on the bus I realized that the tin heart was gone....
