A
Mr. White works in an office. He liked reading in bed when he was at school. It was bad for his eyes and now he is near-sighted. But he wouldn't want anybody else to know about it and he never wears a pair of glasses. It often brings him some trouble.
One winter morning he was sent to a village school on business. He got off a bus at a stop in a small town. Then he had to walk there. The road to the village wasn't smooth. There were stones here and there. He fell over several times and it made his clothes very dirty. At last he got to the village. Suddenly it began to blow strongly and it got much colder. His hat was blown off while he was looking for the school. He had to run after it but he couldn't catch it. He was wondering why his hat ran into a house as if it had legs. And then he ran into the house, too.
A big woman appeared and stopped him by shouting angrily, "What are you running after my hen for?"
