An English student went to a city in Australia to study. He walked around the city to look for a warm room. One evening he was walking along the street with a map. He saw a small board in the window of a house. The word “Room ”was on it. “What a nice room it is!” he said, “the windows are in the south side. The sun will come into the room during the day.
