Once there was a young boy who had quite a collection of remote control cars, toys, and even a small airplane or two. He took good care of them, and had them arranged nicely on a shelf in his bedroom. Occasionally, he would take one of the cars down and play with it by hand on the floor of his bedroom, but for the most part he just arranged them, painted some of them, put decals on others, and just looked at them. For some reason, he was quite satisfied.
One time a friend of his came over to play and when they went up to his bedroom, he saw his friend’s collection and nearly burst with excitement. “My cousin has one of those,” he said. “It flies great. Let’s take it out to the back lot.” The other boy shook his head no.
“Why not? Are you afraid of wrecking it? My cousin says they are really built tough.”
“No, that’s not it.”
“Well, why not then?”
“Well, I hate to pay for batteries.”
