Аn old tale.

Once a little old woman backed cakes in her over. She had on a black dress and a small white apron. A red cap was on her head. A poor old man came to her kitchen door and said, " I am hungry, good woman, please give me one of your cakes." The old woman said, "These cakes are too large for you. I shall bake you a little cake." So she made a very little cake and put it into the oven. But the cake began to grow bigger and bigger. "This cake is too large," said the old woman. But it began to grow bigger too. "I shall not give you this cake," said the old woman, "it is too large for you." Then she made a tiny cake again and put it into her oven. But that cake began to grow bigger and bigger. "I don`t want to give you any cake," said the old woman. "I shall eat them but not you. Go away." So the poor old man went away hungry. Now comes the strangest part of this story. As the old woman began to eat her cakes she began to grow smaller and smaller. Her nose became a sharp bill. She looked at her arms. And what did she see? She saw black wings. She looked at her black dress and white apron. But they were all feathers. Now she was a bird. You can see this little bird. She hops up and down the trees and looks for worms. You will know her when you see her. People say that the old woman who did not want to give one tiny cake to a poor old man is now a woodpecker.
