　　(2010届英语周报第20期)It was a half-hour before midnight on December 24th. I was a ticket counter supervisor(主管) for a major airline and was looking forward to the end of my shift(班)at Stapleton International Airport in Denver. My wife was waiting up for me so we could exchange gifts.

　　A very worried gentleman approached me. He asked how he could get home to Cheyenne, Wyoming. He had just arrived from Philadelphia and missed his connecting flight. I pointed him to the ground transportation area. There he could rent a car. And then I called my wife to let her know I would be home shortly.

　　About fifteen minutes later, the gentleman returned and informed me that all the buses were full and there were no cars available. I told him he had to stay for a night. Hearing that, he burst into tears.

　　He explained that his name was Tom, and his son was seriously ill and was not expected to live another year. He expected that this would likely be the last Christmas with his son.

　　I told Tom to collect his luggage and wait for me. I called my wife Kathy and told her not to wait up for me. I was driving to Cheyenne. We arrived in Cheyenne around 2∶30 A. M. .

　　Kathy was waiting up for me when I got home. We traded gifts and then our conversation concerned Tom. For Kathy and me, there was no question that driving Tom to Cheyenne was the only option.

　　A couple of days later, I received a Christmas card with a picture of Tom and his family. In it, Tom thanked me for the special gift he had received that holiday season, but I knew the best gift was mine.
