Last Sunday, I was on my way home after doing some shoppings in a supermarket. I stood on the road side and watched the traffic careful. When I saw it was safe, I begin to cross the road. All of sudden, a motorbike came over knocking me down but my things went all over. Thankfully, he was driving slowly and I had my leg injure a little. The driver apologized to me and called a taxi to send me to the nearer hospital in the town. I visited to a doctor on duty, and I was told there was something serious. The motorbike driver insisted on my paying the money for my medical examination, but I refused.
