A beautiful, expensively dressed lady complained to her psychiatrist (精神病医师) that she felt that her whole life was empty; it had no meaning.
So the psychiatrist called over the old lady who cleaned the office floors, and then said to the rich lady, “I’m going to ask Mary to tell you how she found happiness. All I want you to do is to listen.”
So the old lady put down her broom, sat on a chair and told her story, “Well, my husband died of malaria and three months later my only son was killed by a car. I had nobody … I had nothing left. I couldn’t sleep; I couldn’t eat; I never smiled at anyone; I even thought of taking my own life. Then one evening, a little kitten followed me home from work. Somehow I felt sorry for that kitten. It was cold outside, so I decided to let the kitten in. I got it some milk, and it licked the plate clean. Then it purred comfortably and rubbed against my legs, and for the first time in months, I smiled. Then I stopped to think; if helping a little kitten could make me smile, maybe doing something for people could __________. So the next day, I baked some biscuits and took them to a neighbor who was sick in bed. Every day I tried to do something nice for someone. It made me so happy to see them happy. Today, I don’t know of anybody who sleeps and eats better than I do. I’ve found happiness, by giving it to others.”
When she heard that, the rich lady cried. She had everything that money could buy, but she had lost the things which money couldn’t buy.
