Leaving a store, I returned to my car only to find that I'd locked my keys and cell phone inside. A teenager riding his bike saw me kick a tire and say a few choice words. "What's wrong?" he asked.

I explained my situation. "But even if I could call my wife," I said, "she can't bring me her car key, since this is our only car." He handed me his cell phone. "Call your wife and tell her I'm coming to get her key."

"That's seven miles round trip."

"Don't worry about it."

An hour later, he returned with the key. I offered him some money, but he refused. "Let's just say I needed the exercise," he said.

Then, like a cowboy in the movies, he rode off into the sunset.
