    Jack lives in a smaller town in England. He usually stayed in his own country during the holidays. Last year, he decided to go to Russia and stayed there for a few day. One day, he went out for walk. In England, people drive on the left side of the road. And in Russia, they drive on the right, which Jack forgot. When crossed a busy street, she was almost knocked down by a car. Jack stood here for a moment, full of fear. Shortly after he recovered from himself, he said: “Where am I?” An old man which sold maps nearby ran to Jack at once and said: “Maps of the city, sir?”
