Living in the city has a lot of pluses. Shops, schools and hospitals are not far from your house. Your friends and relatives can easily get to your place by bus or on foot. You can never be absolutely alone in the city with so many people around you all the time. Yet living in the city has some bad sides too. One of them is pollution. Thousands of cars and public transports pollute the city's air. Another bad side is a lot of noise. Street noise, noise coming from your neighbours do a lot of harm to our nerves. Fresh air, beautiful quiet landscapes can hardly be found in big cities.

She didn't know where to go. "How I can get out from here?" - she has asked. "You can't find the road?" – suddenly she has heard a voice. She has looked up and down, but has seen nobody. Near the place where she stood, there was just ugly old tree. Then she has heard a voice again: "Speak louder! I don't hear you! You were taught to speak English at school?" Sara has understood that the tree talks to her. "Sit down, please", - Sara has told. "I look for magic seeds of mustard." "At the acetic witch can be a little, but I isn't sure", - has told a tree. "The way to the lock of the witch is to the left of the road conducting to the magic airport." "You could repeat, please?" - Sara has told. "It is very difficult to remember it." "Of course, isn't present", - has told a tree." You, youth, have to learn to work without assistance. Well, hurry up!" And it has sadly shaken leaves. Sara has gone forward. It was difficult to go because it was dark. She wanted to get on a bus, but there were no buses in the wild wood. So she had to walk. It was the long way. By then, she has seen ведьмин the house, there was a morning. She has approached the lock and has seen that the key was at doors. She has opened her and has entered. "Approach here!", - she has heard a voice from above. She has approached and there she has seen the big room. In the middle of this room fire burned. Before fire there were two chairs, and in one of them there was an ugly old hag. Her friendly black cat, Midnight, was in another.
