помогите перевести пожалуйста очень срочно а то переводчик что попало переводит. Вот это:
If you ask your mother if she knew about Peter Pan when she was little girl, she will say,” Why, of course I did, child.” And if you ask her if he rode on a goat in those days, she will say. “What a foolish question to ask. Certainly he did.”
Then if you ask your grandmother if she knew about Peter Pan when she was a girl, she also says. “Why, of course I did, child. “But if you ask her if he rode on a goat in those days, she says that she never heard that he had a goat. Perhaps she has forgotten, just as she sometimes forgets tour name and calls you Mildred which is your mother’s name.
Goat or no goat it shows that Peter is very old but that really he is always the same age. His age is one week. When he was seven days old he went out of the window and flew to Kensington Gardens. If you think that he was the only young child who wanted to do this it shows how you have forgotten your own young days. Think very hard and you will remember that you wanted to go back to the trees just as the birds.
When Peter Pan stood on the windowsill he could see the trees in Kensington Gardens. When he saw them he forgot that he was a little boy in pajamas and he started to fly. He flew over the houses to the gardens. It is wonderful that he could fly without wings. He came down on the grass and started to play. He already didn’t know that he was a little boy. He thought that he was a bird. When he tried to catch a fly he couldn’t because he tried whit his hand which a bird never does. He saw a lot of fairies. They were all very busy and didn’t see him. He was thirsty now, son he flew to the pond to have a drink. He tried to drink like a bird but forgot that he didn’t have a beak but a nose.
Then he wanted to sleep. At first it was hard to be comfortable on the branches of the trees but soon he learnt and fell asleep. He woke up in the night. As everybody knows what seems a warm night to a bird is a cold night to a boy in pajamas.
Peter wanted to talk to the fairies but to his surprise they all ran away and hid when he came near. They shouted, “There’s a boy in the park.” Peter never thought for a moment that he was the boy because he was a bird. He wanted to talk to the birds but he couldn’t find any to talk to. They all flew away. Every living thing ran away or flew away from him. Poor little Peter Pan! He sat down and cried. But even if he thought he was a bird he did not sit as a bird does. Happily he did not know this and so he didn’t lose his faith in the fact that he could fly. Why can birds fly and we can’t? It is only because they have faith, because to have faith is to have wings.
