An Italian was once visiting in London. He didn't know English yet, he stayed in a motel which owned by someone who could speak Italian well.
            “I would like to walk around the city, but I’m afraid I will get lost.” He said to the owner of the motel.
            “You have to remember the names of the streets that you will pass.” Said the owner. “If you can’t remember them all, you will have to copy them into your notebook.”
            So the Italian left the motel and started to look around. He also wrote the names of the streets that he had passed into his notebook. Then he walked on. Finally, he got lost.
            Two hours later he came to a police office. With the help of his gesture, he explained to the police officer that he didn’t know the name of his motel, but he did know the name of the street where the motel was because he had written it in his notebook. But while he showed it, the police officer was surprised and directly laughed at him. Because that was written “One Way Street” XD
