Once upon a time there lived a tiny girl, whose parents often called her a noisy chatterbox. One day they asked their daughter to go to the forest and pick some mushrooms here and give her a container for it. The girl went to the forest and began picking. While she was listening fascination singing of birds, the girl didn't noticed a wicked witch standing beside her. But suddenly all birds stopped singing and the girl turned her head to see what are they afraid of. She saw the witch; she was so dreadful! The witch began to whisper her fateful spell; but the girl didn't run away. She just smiled and began to talk about different things: about weather today, about her own cat, about her travelling with parents by their car and also a great deal of wonderful things. Witch stopped her whispering, but the girl continued talking. She had only one edition - so the disappointed witch disappeared. The girl laughed; the disappointed witch with sad face made an unforgettable impression on her. So, her adventure has finished, and the girl took her container which contains were a great deal of mushrooms, and came around to her home.
