The lesson adults can learn here is that the world is filled with things for our enjoyment. The trick is to open our eyes and look for them. They can find a penny on the sidewalk and feel rich. They can find a fossil-shaped rock and feel like Indiana Jones. They can find an anthill and feel like God.
Kids find enjoyment in the simplest of things.
You can too. In Woody Allen's movie musical, Everyone Says I Love You, there is a scene in a funeral parlor. Suddenly all of the corpses jump out of their coffins and start to sing and dance. Than You Think. Kids don't need to learn the song's message, they are masters of enjoyment.
