Нужен точный перевод, литературный. Без переводчиков.

One day when Pooh Bear already had visited some of his friends and had nothing else to do, he thought he would go round to Piglet`s house to see what Piglet was doing.

It had been snowing since early morning.

Pooh expected to find Piglet warming his toes in front of his fire, but to his surprise he saw that the door was open, and the more he was looking inside the more Piglet was not there.

"So what will I do," said Pooh, "is this. I will go home first and see what the time is, and perhaps I will put a scarf round my neck, and then I *ll go to see Eeyore ahd sing my new hum to him."

He hurried back to his own house; when he opened his door he suddenly saw Piglet sitting in his best armchair and looking as if he had been sitting there for a long time. Pooh could only stand there wondering whose he was in.

"Hallo, Piglet," he said. "I thought you were out."

"No," said Piglet."it`s you who were out. I have been sitting here for an hour already."

Pooh looked up at his clock, which had stopped at five minutes to eleven some weeks before.

"Nearly eleven o`clock," said Pooh happily. "You are just in time for a little something," and he put his head into the cupboard.

"And then we *ii go out, Piglet, and sing my song to Eeyore". "Which song, Pooh?"

"The one we are going to sing to Eeyore," explained Pooh. The clock showed still five minutes to eleven when Pooh and Piglet set out on their way half an later.
