Last Friday, I rode on my bike home. At a crossing, I accidentally knock an old man off his bike. I hurried over and found his leg was injured. Nervous and worrying, I called my mom and told her that had happened. We took the old man to the hospital at once. The doctor gave him careful examination. To our delight, there was nothing serious wrong with him.
Then, we went back to where the bike was parked. For our disappointment, the bike didn’t work. I immediately got it fixed. The old man got on my bike and we waved goodbye to each other.
The accidents made me realize that we should be careful to avoid get into accidents, but once they occur, we should take responsibility.
