One summer evening as I was cooking dinner, there was a knock at the door. I opened it and saw an old man. But his voice was pleasant as he said, “Good evening. I come to see if you have a room for just one night. I live far away from here, and there's no bus till next morning. ”

I told him we would find him a bed, but it was not comfortable. I went inside and cooked dinner. When we were ready, I asked him if he would like to join us. “No, thank you. I have plenty.” When I had finished the dinner, I went out to talk with him. He told me he fished for a living to help his daughter, her five children, and her husband, who was ill and too weak to do anything.

At bedtime, we put a bed in the children's room for him. On his next trip, as a gift, he brought a big fish and some fresh vegetables. In the years he came to stay overnight with us, and there was never a time he did not bring us some fish or vegetables from his garden.

I know it was thankful for our family to know him, from whom we learn what was to accept the bad without a complaint(抱怨) and the good with thanks.
