     Many years ago, when I was fresh out of school and working in Denver, I was driving to my parents'

home in Missouri for Christmas. I stopped at a gas station (加油站) about 50 miles from Oklahoma City,

where I was planning to stop and visit a friend. While I was standing in line at the cash register (收款台),

I said hello to an older couple who were also paying for gas.

     I took off, but had gone only a few miles when black smoke poured from the back of my car. I stopped

and wondered what I should do. A car pulled up behind me. It was the couple I had spoken to at the gas

station. They said they would take me to my friend's. We chatted on the way into the city, and when I got

out of the car, the husband gave me his business card.

     I wrote him and his wife a thank-you note for helping me. Soon afterward, I received a Christmas present

from them. Their note that came with it said that helping me had made their holidays meaningful.

     Years later, I drove to a meeting in a nearby town in the morning. In late afternoon I returned to my car

and found that I'd left the lights on all day, and the battery (电池) was dead. Then I noticed that the Friendly

Ford dealership－a shop selling cars－was right next door. I walked over and found two salesmen in the

showroom.

     "Just how friendly is Friendly Ford?" I asked and explained my trouble. They quickly drove a pickup truck

to my car and started it. They would accept no payment, so when I got home, I wrote them a note to say

thanks. I received a letter back from one of the salesmen. No one had ever taken the time to write him and

say thank you, and it meant a lot, he said.

     "Thank you"－two powerful words. They're easy to say and mean so much.
