I was sitting at my favorite table in a restaurant last Sunday and wait for the food I had ordered to arrive. I suddenly found that Lin Ling, one of my classmate, worked like a waitress there. Honest speaking, it was great surprise for me to find her working there. As far as I know, she’s from a richer family. What was it that made her to work there? I walked up to her and asked her the reason. When asking, she said, “I just want to earn some pocket money so that we can help some children in poor areas go back to school.” How a good girl! I should learn from her.
