One afternoon, it was drizzling. I was on my way home by train. There were only a few passengers in the carriage. When the train reached the station in front of a bridge, two impressive passengers got on, an old and a young. They looked like father and son. And they were both disabled. The old man was blind.The little boy of eight or nine years old had only one eye open,the other closed tightly. The little boy took pains to move with his father. As the train started rumbling again, the little boy's voice got around, "Grandpas, grandmas, uncles and aunts, my honor to meet you. I'm Xiao Ming. Now I will sing a song for you."
