The face of a boy, glimpsed in passing by the side of the road... who smiles in wonder and delight at the passing Rider from a foreign land...

The boy grows into a man, still smiling, surrounded by his family -- wife and children...

The man becomes old, his face wrinkly, and now sits in a rocking chair by the side of the road, smiling at the traffic that passes him by...

...with no longer any memory of the Rider that passed by, so many years ago...
