The trip was short. A few minutes later, the magic plane was under a large old tree. Sarah was in the middle of a wild forest. She didn't know where to go. "How can I get out of here?" "what is it?" she asked. "You can't find your way?" suddenly she heard a voice. She looked up and down, but saw no one. Next to where she was standing, there was just an ugly old tree. Then she heard the voice again: "Speak up! I can't hear you! Didn't you learn to speak English at school?" Sarah realized that the tree was talking to her. "Please sit down," Sarah said. "I'm looking for magic mustard seeds. ""The vinegar witch may have some, but I'm not sure," the tree said. "The way to the witch's castle is to the left of the road leading to the magic airport. "" Could you repeat that, please? " said Sarah. "It's very hard to remember. ""Of course not," the tree said. "You young people should learn to work without help. Well, hurry up! " And it shook its leaves sadly. Sarah went ahead. It was difficult to walk because it was dark. She wanted to get on the bus, but there were no buses in the wild forest. So she had to walk. It's been a long journey. By the time she saw the witch house, it was already morning. She went to the lock and saw that the key was in the door. She opened it and went in. "Come here!" she heard a voice from above. She walked over and there she saw a large room. There was a fire burning in the middle of this room. There were two chairs in front of the fire, and in one of them was an ugly old witch. Her friendly black cat, Midnight, was in the other one.
