The first time I remember noticing the crossing guard was when he waved to me as I drove my son to school. He __1__ me with a puzzle—all because he waved to me like someone does __2__ seeing a close friend. A big, __3__ smile accompanied his wave. For the next few days I tried to __4__ his face to see if I knew him. I didn't. Perhaps he had __5__ me for someone else. By the time I contented myself with the __6__ that he and I were strangers, we were greeting each other warmly every morning like old friends.
Then one day the __7__ was solved. As I __8__ the school he was standing in the middle of the road __9__ his stop sign. I was in line behind four cars. __10__ the kids had reached the safety of the sidewalk, he lowered his sign and let the cars __11__. To the first he waved and __12__ in just the same way he had done to me over the last few days. The kids already had the window down and were happily waving their reply. The second car got the same __13__ from the crossing guard, and the driver, a stifflooking(表情刻板的) businessman, gave a brief, almost __14__ wave back. Each following car of kids on their way to school __15__ more heartily.
Every morning I continued to watch the man with __16__. So far I haven't seen anyone __17__ to wave back. I find it interesting that one person can make such a(n)__18__ to so many people's lives by doing one simple thing like waving and smiling warmly. His __19__ armed the start of my day. With a friendly wave and smiling face he had changed the __20__ of the whole neighborhood.
