It is a short, simple scene right out of the heart of America.

The little boy and his best friend are walking along on a country road.  The big dog is a gentle, yet protective presence.  All of a sudden they come to a little puddle in the middle of the road.  Now, everybody knows that a small boy just can't pass up a puddle.  So the little boy stops and goes to explore.  The big dog, mindful of his implied responsibility  stands perfectly still.  Soon the little boy has satisfied his curiosity about the puddle and rejoins his faithful companion on their walk.

No words are spoken.  None are needed.  How sweet is this....
