When I was young, I liked to play jokes on people I knew, especially on my parents and friends. One day my mother was cooking in the kitchen and my younger brother was playing near the window. I ran to my mother and said, “Mum, Brother John has fallen from the open window!” She was very worried about my brother and then I said, “Don’t worry. I’m just joking.” And my mother shouted at me, “ If you do it again, I’ll punish you.”
One day I went swimming with my friends in the sea. I wanted to play a joke on my friends. In the beginning, I went swimming alone, and I called to my friends, “ Help me!” All my friends came to help me, only to find out that I was joking. But the next time I wasn’t joking. I swam in deep water and I was so careless that I was almost drowned（淹死）. I tried my best to call my friends for help, but this time nobody came to saved（救）my life. They took me to the emergency center. From then on, I haven’t joked on anyone. I think this is the best lesson in my life.
