A few weeks ago, just before 6:00 , my wife and I boarded a taxi to begin the last lap of our trip to Salt Lake City from Australia. Our driver, who had been on duty since 3:00 , was anxious to talk with us, his first passengers of the day. We learned his parents were born just outside of Mexico City. They moved to Chicago, where he was born, and then moved to New Mexico. Twenty years earlier our friend had come for a short visit to San Francisco and had never left. During our trip to the airport, this man related a few incidents from which some great truths were reemphasized.
