As the bus came to a stop at the light, I glanced over and out the right side window just as a young boy, a few feet away on the sidewalk, came into view. Perhaps 7, 8, or 9, he looked to be of Asian descent and was in motion, beaming — like he was joy incarnate— and carrying what looked to be a paper airplane. He dodged and laughed as he was chased by an older, taller boy who looked to me to be 11 or 12, also of Asian descent, but definitely not laughing. In possession of his own paper airplane, the older boy attempted to launch it at the younger. But falling short of its target before succumbing to gravity, its only noticeable impact was to cause the younger boy to laugh with even more glee and launch his airplane in retaliation. His, too, fell short of the intended destination. Then my bus continued on and both boys moved out of frame, and I resumed the rest of my journey accompanied by the memory of his smile.
