Dear editor,

     I am writing to ask what has happened to our young people. They are not as polite or hard-working as

my generation (一代人). I will give you two examples.

     Last Friday, I got on the underground at 9:15 a.m. It was very crowded so there was no free seat. There

were some boys sitting on the seats near me. I didn't know why they were not at school. They were talking

and laughing loudly. It was difficult for me to read my newspaper with all the noise. At the next stop, a

pregnant (怀孕的) woman and her daughter got on with lots of shopping bags. I expected the boys to let them

sit down. They saw the woman but they did nothing. I had to ask them to give the woman and her daughter

seats. They did so but gave me a rude look.

     Last Saturday, I had dinner with my friend's family. I was glad to see his children, who I hadn't seen for

ten years. During the dinner, I started talking about world politics with the children. It soon became clear that

they didn't know much about it. They couldn't tell me the name of the King of Spain or President of Italy. All

they knew about was the Internet or which singers were the most beautiful. In my days, students knew the

kings, the queens and the presidents of every country in Europe.

    I worry about the future of Germany. How could these young people become good 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 some readers can give us some ideas about what to do with this "lost generation".

                                                                                                                                  Yours sincerely,

                                                                                                                                   Frantz Vogts
