B I was traveling alone through the UK . To reach places that were off the public transportation map ,I bought an old car, which cost most of my money. I couldn’t afford to stay in the hotel, so I had to camp in my car for the rest of the trip. One morning I awoke in my old car on a country road in Ireland and saw a single house. The water in my thermos ( 保温瓶)had gone cold, so I knocked on the door of the house. A woman opened it. I asked her for some hot water. But she wouldn’t let me get away with just that! I was invited indoors. She asked me to sit at the table and have breakfast with her family. They filled my thermos before I left. I was greatly moved. And I decided to pass the kindness on. The other day I met a young man who had been driving around to look for a parking lot. He looked increasingly upset. I was glad that I was able to point one out to him. His thankful smile was the hugest reward ( 奖赏)for me.
