One day, when I was ten years old, my father bought a motorcycle. I think it was small light object and easy to ride it. I persuaded my father to teach me to ride. First, my father refused it and promised that he would teach me two or three years later, but I still whimpered. Finally, my father surrendered and promised to teach me.

    He began to teach me riding the motorcycle around a field in my village. My father was very patient to give me some directions. I was very happy at that time.

    One day later, when I was alone at home, I intended to try my riding ability. So, I tried myself. But when I was going back home and I must have passed through a narrow slippery street, I got nervous. I lost my control and I fell into the ditch.

    After that, I told my father about the last accident. I was scared that my father would be angry and never let me ride again. But the fact is my father was very proud of me. He just gave me some advice and since that accident, I got my father's permission to ride motorcycle.
