When I was a child, I really 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," My brother 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. At 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. I tried my best to call my friends for help, but this time nobody came to save my life. Finally, 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.
