One day a very hungry soldier came to an old woman's house

One day a very hungry soldier came to an old woman's house. He was very tired and hungry. He asked if he could stay there for a night. The old woman let him in. She told that he could sit by the fire to warm himself. The soldier did so. The old woman told that there she had nothing to eat. The soldier said that he could cook a soup from nothing if the woman would give him a pan. She did. He poured some water in the pan. He asked the woman to give some rice. She gave. Sometime later he asked potatoes and butter. The old woman gave him potatoes and butter. When the soup was ready the solder asked some salt. Soon the soup from nothing was ready. They sat at the table and ate it.
