The first time I remember noticing the crossing guard was when he waved to me as I drove my son to school. He (31) me with a puzzle-all because he waved to me like someone does on seeing a close friend. A big, (32) smile accompanied his wave. For the next few days I tried tO study his face to see if I knew him. I didn’t. Perhaps he had (33) me for someone else.

With a friendly wave and smiling fade he had changed the feelings of the whole neighbourhood.
