(C)      A young man was driving down the road, and it was getting dark and beginning to snow. Suddenly he saw an old lady standing on the side of the road and waving her hand. The young man pulled over to see what was happening. The old lady’s car had a flat tire, and it seemed too big a problem for her. The young man said, “Don’t worry, ma’am. My name is Joe, and I can help you out. It’s really cold now. You can stay in my car to keep warm.” After Joe changed a tire, the old lady asked how much she had to pay for it. Joe just smiled at her and said to her, “Never mind. If you really want to thank me, you can help other people in need. And think of me when you do it.”　　      After the old lady drove a few miles down the road, she felt hungry and got something to eat at a diner. The waitress came over and her smile was as bright as the sun. When she found the old lady’s hair was wet with snow, she gave her a clean towel to dry her hair. The old lady noticed the waitress’ uniform was quite worn. Suddenly the old lady thought of Joe. She finished her dinner and paid with a $100 bill. When the waitress was about to get the change, the old lady turned around and left. Then she saw a few lines on a note, “You don’t need to pay me back. Please help another person in need. When you do it, think of me.”　　      The waitress didn’t know what to say. She never had such a large tip. The lady must be an angel, she thought. One hundred dollar was not big money, but God knew how badly she and her husband needed every penny they could make. The waitress knew how worried her husband was, although he just worked hard and never showed his anxiety. That night, when she got into bed, she kissed her husband softly and whispered, “Everything’s going to be alright. I love you, Joe.”
