Перевидите,срочно!!There once was a man who lived alone in a little house in a small town. He always cooked his own dinner, cleaned the house by himself, and made his own bed.
One night he came home feeling very hungry, so he made a big dinner. He had been eating much and he was very tired after finishing. He decided to leave the dishes till the next night.
But the next night he was TWICE as hungry, so he cooked TWICE as big of a dinner, and it took TWICE as long to eat it, and he was TWICE as tired as he had been the day before. As the days passed by, he got hungrier and more tired, and there were so MANY dirty dishes that he started to pile them on the table.
As soon as the table was full he started to put them on his bookshelves. As soon as THEY were full, he had been piling them on the floor for several days and soon he couldn't get into his house!
One night he looked in his cupboard and found out that there wasn't any clean dish there. Soon he used up all his ashtrays and clean flowerpots, and his sweets dishes, and drank water from vases. He used up EVERYTHING, even the pots he cooked his food in, and the frying pan, and the

kettle, and he didn't know what to do! He was SO unhappy. His whole house was full of dirty dishes, and dirty flowerpots, and dirty ashtrays, and dirty sweets dishes, and dirty pots, and a dirty soap dish, and a dirty frying pan, and a dirty kettle. He couldn't find his books or his clock, or even his BED any more! He couldn't sit down to think because even his chairs were all with dishes, and he couldn't find the sink so he could wash them!
But THE RAIN STARTED! And the man got an idea. He drove his big lorry around to the side of his house and piled all the dishes, and all the vases, and all the ashtrays, and pots, and a frying pan, and a kettle on it and drove the truck out into the rain.
