A Frenchman is once visiting London. He wished to take a walk to see a city. But he was afraid he might get being lost because he knew no words of English. So after he left his hotel, he stopped on the first corner and carefully copied in his notebook the names of the street where he was staying. Then he walked on. At last, he got lost. In several hours he found a policeman .The Frenchman tried his best to explain the policeman that he didn’t know the name of his hotel, and  he knew the name of the street. He then showed the policeman that he copied in his notebook. It was read : “One-way street”.
