Humour is not only considered as one of the most valuable quality, but necessary for a delightful life. You can clear sense humour when staying with Joe. He is kind but overweight, who brings him much trouble. Once after class one classmate asked about him, “Why are you so fat?” We both stopped to stare at him, wondering how Joe would answer the question. He just said at a calm voice, “Well, because my size must large enough to hold my large heart of love.” Heard his words, we burst into laughter. Not only did Joe took the joke, but he managed to deal with the embarrassed situation.
