Mr. Green is quiet and doesn't like talking with people. He likes reading newspapers and playing computer games. He never exercises. Sometimes he watches soccer or basketball games on TV. He likes milk very much and drinks it three times a day.

Mrs. Green is a bank clerk. It's a busy but boring job. She works with people and money every day. So she is always tired after work. She likes to take a good rest and goes to bed early after dinner. Usually she goes to bed at 8:30 in the evening and gets up at 6:30 in the morning. Mr. Green is very happy with that. But Mrs. Green isn't because Mr. Green always talks in her sleep.

One morning, Mr. Green sat at the table and had breakfast. Mrs. Green asked him “Why do you always talk in your sleep?” Mr. Green said “Because I have few chances to talk in the daytime”

The next morning after their children all went to school. Mrs. Green asked Mr. Green angrily “Why did you scold（骂）me in your sleep last night?” “Because I'm afraid to do it when I'm awake（醒着的）.”

Be honest. That's all you have to do on Honesty Day. It would be great if we were all honest every day of the year. It's good that there is a day to encourage honesty. M. Hirsh Goldberg started Honesty Day. He chose the last day of April because the first day is April Fool's Day, which celebrates lies. On Honesty Day, anyone may ask you any question and you should give a true and honest answer. That means that you have knowledge of Honesty Day.

M. Hirsh Goldberg wrote a book on telling lies. He said in his book that almost all person lie about 200 times a day. In our daily life, a typical（典型的）life for a man is “I did not drink that much” and for a woman is “Nothing is wrong, I'm fine.” It is found that nurses are the most honest people, while sales people and politicians（政客）are the biggest liars.

Every Honesty Day, M. Hirsh Goldberg hands out prizes to honest people.

Paris is a very beautiful city but I will not call it the most romantic（最浪漫的）city at all! It is difficult to find a hotel（旅馆）! That is quite funny（滑稽）．Some policemen help us and then we find a hotel! The hotel is on the sixth floor and it is tired to climb up the stairs（爬楼）! The room is very simple（普通的）but it has a big bathroom．We go out for a walk to visit the city. The Louvre Museum is our favourite one. There are some wonderful pieces of art there. The Eiffel Tower looks so cool from a far place, but when we get close to it, it doesn't look so good. We also don't feel well about the expensive food. Most of the time, we enjoy Paris, but the weather is not always good. It often rains. We feel a little difficult because not many people can speak English and we can't speak French. But I'm still（仍然）glad that this is the beginning of our travel.
