Passing through the Atlanta airport one morning, I caught one of those trains that take travelers from the main terminal to their boarding gates. Free, and impersonal, the trains run back and forth all day long. Not many people consider them fun, but on this Saturday I heard laughter. At the front of the first car – looking out the window at the track that lay ahead – were a man and his son.

We had just stopped to let off passengers, and the doors were closing again. “Here we go! Hold on to me tight!” the father said. The boy, about five years old, made sounds of sheer delight.

I know we’re supposed to avoid making racial distinctions(种族歧视) these days, so I hope no one will mind if I mention that most people on the train were white, dressed for business trips or vacations.

As I got off, I remembered some thing I’d wanted to buy in the terminal. I was early for my flight, so I decided to go back.

I did – and just as I was about to reboard the train for my gate, I saw that the man and his son had returned too. I realized then that they hadn’t been heading for a flight, but had just been riding the shuttle.

“I want to ride some more!”

“More?” the father said, mock-exasperated(嗔怪模仿) but clearly pleased. “You’re not tired?”

“This is fun!” his son said.

“All right,” the father replied, and when a door opened we all got on.

There are parents who can afford to send their children to Europe or Disneyland, but the children turn out rotten. There are parents who live in million-dollar houses and give their children cars and swimming pools, yet something goes wrong. Rich and poor, black and white, so much goes wrong so often.

“Where are all these people going, Daddy?” the son asked.

“All over the world,” came the reply. The other people in the airport were leaving for distant destinations or arriving at the ends of their journeys. The father and son, though, were just riding this shuttle together, making it exciting, sharing each other’s company.
