The most unforgettable experience in my life was a car accident which I saw by myself.  Although it happened many years ago, I can still recall it clearly as it happened just now.

    When I was an elementary school student, one day, Father and I went for a drive.  Just when we stopped for a red light, suddenly, I heard a sound "pang" and then, I raised my head for taking a look.  OH!  I saw an old man hitting by a car.  He laid on the road and cried loudly, with his face fulled of painful expression.  The ground around him was filled with blood.  I was sure that he got severely injured.  Soon, the traffic light turned green, and Father drove away quickly.  I took the last glance at the old man, and felt he was badly poor.

    Because of seeing this accident, I was deeply afraid that if one day I may suffer from such an horrid accident.  Afterwards, Father told me "if that car had not run through the red light, the car accident would not have happened.  So, he asked me to be sure to obey the traffic rules.  Having such an unforgettable experience, I have really been a careful pedestrian from then on.
