    I was driving home from my laughter club when I passed a patrol policeman going in the opposite direction. I looked in my rear-view mirror(后视镜)and saw him make a quick Ilium. I looked down at my speedometer(速度计)and saw that I was going at the speed of 65 mph. He got behind me and started flashing those pretty red and blue lights. I could feel my heart pounding.

I am a Laughter Yoga Teacher. I teach people that laughter is the best medicine for stressful situations, so I decided to practice what I teach. I started laughing, not because it was funny, but because I know that laughter can reduce blood pressure and make people happy. The police officer walked to my car. When I rolled down my window I was giggling (笑)to myself.

''Did you know you were going at 75 mph in a 55 mph zone? '' he shouted. I tried to keep laughing and said ''No'' with a smile, I looked clown and saw that I was going at 65 mph. He responded, ''That is still breaking the law. The speed limit is 55. ''

I was thinking about the laughing. ''Ha ha ha, I made a mistake and I will learn a lesson from it Please forgive me''. I kept giggling to myself while he asked about my driving record. Then I laughed out loud when I explained to him, ''I used to get letters in the mail stating if I got one more ticket my license would be revoked'', I went on to say, ''when I was a teenager and in my early twenties. I haven’t had a ticket in at least 10 years. ''

He took away my license and went back to his police car. I could see him writing through my rear-view mirror. Soon he came back to my car, handed me back my license, smiled and said, ''Slow down, and have a nice day. ''

I believe that the laughter and smile changed him.
