Dear Editor, I am writing to ask what has happened to the young. They are not as polite, hardworking or clever as my generation (一代人). I'll give you an example. Last Friday I got on the underground at 9:15 a. m. It was very busy so there were no free seats. There were some teenagers (青少年) sitting on the seats near me. I don't know why they were not at school. They were talking loudly and laughing. It was difficult to read my newspaper with all the noise. A heavily pregnant (怀孕的) woman and her daughter got on at the next stop, with lots of shopping bags. I expected the teenagers to let them sit down. They slowly did so but gave me an impolite look. I got off at the next stop and was glad that the teenagers didn't follow me. I worried about the future of our country. How could these young people become responsible (有责任心的) workers and parents? They sit around McDonald's after school instead of going to the library as I did at their age. Maybe they have too much money. Perhaps another reader can give us an idea about what to do with this "lost generation". Franz Johnson
Dear Editor, I read Mr. Johnson's letter about the problem of today's youth (青少年) with much interest. He described teenagers on a train not giving seats to a pregnant woman and her daughter. I was the woman. We must have seen things differently. I found the teenagers helpful and kind. Did Mr. Johnson see the teenagers help me off the train? Did he see them carry my shopping bags to a taxi for me? Did he see them friendly to my daughter? Obviously (明显地) not. "Older" people often say today's youth isn't as good as their generation. Their parents said that about them. Mr. Johnson must accept (接受) that the world is changing and young people are changing with it. I find today's youth mostly kind and more friendly than my generation. Perhaps Mr. Johnson should really try to get to know some young people before he calls them the "lost generation".
