I never thought I would have a life-changing experience at Wal-Mart.

      Although my thoughts were only on speed, the checkout line I was standing in wasn't moving as quickly as I wanted, and I glanced toward the cashier.

      There stood a man in his seventies, wearing glasses and a nice smile. I thought, well, he's an old guy! For the next few minutes I watched him. He greeted every customer before scanning the items. Sure, his words were the usual, “How's it going?” But he did something different-he actually listened to people. Then he would respond to what they had said and engage them in brief conversation.

      I thought it was odd. I have grown accustomed to people asking me how I was doing simply out of robotic conversation habit. After a while, you don't give any thought to the question and just mumble something back. I could say, “I just found out I have six months to live,” and someone would reply, “Have a great day!”

      But that wasn't the end.

      He gave them the change, walked around the counter, and extended his right hand in an act of friendship. He looked at the customers in the eyes. “I sure want to thank you for shopping here today,” he told them. “Wish you have a great day. Bye-bye.”

      The looks on the faces of the customers were priceless. There were smiles and some sheepish grins. All had been touched by his simple gesture-and in a place they expected. They would gather their things and walk out, smiling.

      Of course, he did the same to me and I got to know his name, Marty.

      Who was the guy? It was as if Sam Walton had come back from the dead and invaded this old guy's body.

      I had never walked away from that shop feeling like that.

    Jack Brown, an office worker, lives in Washington. He inherited（继承）a million dollars when he was 23, but he wasn't happy at all. When his college friends were looking for their jobs, he didn't have to. Jack decided to keep living a simple life like everyone else. He gave $ 10,000 of his money to a charity to help poor children live a happy life. Today he is 36. He still wears cheap shoes and clothes and drives a small car only, but he is very happy.

    Up to now Jack has helped some children from poor countries all over the world, by sending them each $200 a month. The money is used for the children's study, food, medicine and clothing. Jack receives a report each year on the children's progress(进步）They can write to each other, but usually the children do not speak English.

    When Jack first heard about these children, he wanted to help them. “It was nothing special,”he said.“Until I went to these countries and met the children I was helping, I didn't know anything about their life.” Once Jack went to meet a little girl in Africa, he said that the meeting was very exciting. “When I met her, I felt very, very happy,”he said.“And I saw that the money was used for a good cause. It brought me happiness. I want to do everything I can to go on helping these children.”

    At the end of the wedding party for Monica and Nick, Monica's mother gave her a new bank saving passbook (存折) as a present. She advised her to put some money in the bank when they had happy things in their life and wrote them down in the passbook. She told her to keep it as a record of her marriage.

    Monica shared her mother's idea with Nick. The following were their deposits (存款) after some time: 7 February: $300, first birthday celebration for Nick after we got married; 15 April: $500, Monica got a better job;…

    However, after years, they began to quarrel every day. One day Monica told her mother that they could not live together any longer and agreed to divorce. Her mother said, "Just do whatever you want to do. But before that, take out all the money in the passbook and spend it."

    So Monica went to the bank. While she was waiting, she took a look at the passbook record. Suddenly the happiness in the past came up to her mind. She went back home, handed the passbook to Nick and asked him to spend the money before getting divorced.

    The next day, Nick gave the passbook back to Monica. She found a new deposit of $5,000 with the words, "This is the day I notice how much I love you and how much happiness you've brought me."
