A good sense of humor can reduction the tension and embarrassment. I still properly remember what happened during my first speech contest. That was chosen by the lottery, Before I want on the stage, I was so tightness when I waited for my turn backstage. Since I never had a opportunity to speak in public, I was afraid. Nevertheless, I still tried my best to ready for it. As it was finally my turn, I tried to stay clam and walked onto the stage with a big smile. But I tripped over the microphone cable and fell on the ground. At that moment, everyone started to laugh at me.
