A story I found on the net (not sure of the website).

She was Lost and Sick

He stood in the middle of the street and called me over in a heavy accent. A lady in a car had that here's-the-map-but-I'm-lost look. We three conferred and then I got in the lady's car and guided her to her hotel. She was in town for a week of medical treatments and had driven 13 hours. It was a beautiful summer evening and I was able to walk home, smiling the whole way.
