When I was 19 years old, I was at a dance club. As we were walking to my car one cold night, a man walked up to us. Behind him was a woman carrying a small child. The child had a jacket on but it wasn’t buttoned up(扣上). The man began to tell us he wanted to borrow some money for the night to get his wife and kid into a hotel. He had a job but no place to live in and was waiting for the first paycheck. He said he could get our mailing address and mail the money back.

The guy I was with reached into his pocket to give this man a $20 bill. As the other man was extending(伸出) his hand out to take the money, I put my hand on my new friends’ hand and said, “Can I talk to you for a minute?”

I told him that every day people asked my mother for money on her way to work. She said they made more money than she did, simply begging for money. These people were scamming those with soft hearts. And if they were truly worried about their child suffering from the cold, they would have at least buttoned his jacket or covered him with his blanket.

My new friend looked at me with disappointment and said, “Michelle, I know there are people out there that make use of others. I also know there are people out there that are one paycheck away from being homeless. If I give $ 20 to 10 people and only one of them really needs it and uses it for the right thing, it is worth it.”

I am now 37 years old and have never forgotten what he said to me. I don’t even remember his name. But I do remember that that experience changed the way I look at different situations.

The automobile industry is spending billions on self-driving cars, but what if we quite like driving?

One holiday a few years ago, I spent hours being transported on trains, buses and planes. I read a novel for a while, then stared out the window, in a black mood. I was turned into goods, being shifted from one location to another. Then, finally, came the exciting section of the holiday when I hired a car.

My wife Jocasta and I followed the positioning system, turning right, then right again, and found ourselves in a small town. I spoke to the positioning system, “We don’t want to be here; we want the highway.” Then it asked me to turn right again and again. With every turn, the street narrowed. The walls were so close that I had to hold my breath.

Another car appeared, coming towards us from the opposite direction. The driver signaled, telling me I had to make way. But how? I didn’t have the courage to back up along the impossibly narrow passage. Soon some locals came to help. One lady stood at the back of the vehicle, waving me on. She continued making “this way, this way” movements with her arms. In an act of blind trust, I followed her instructions, creeping (小心行进) backwards and forwards. Remarkably, it worked. I completed my turn into the side street. The other car passed and the driver gave me a grateful wave. Then I followed the lady’s suggestion and — finally — saw the highway.

My hands were shaking. I breathed in and out. Jocasta turned to me. “You’re my hero,” she said. I looked at her, expecting a shadow of a teasing (嘲笑的) smile, but can find none. “You’re my hero,” she repeated. “I mean it. You did a really good job.” Finally, I managed to steady my nerves. Then we set off again and the car sped smoothly away. Who would exchange all this for a self-driving car?
