Переведите текст: One day Petey, who was a puppy, said to his mother, who was a dog: I'd like a boy for Cristmas".
His mother said she thought he could have a boy if he was a very good puppy.
So the day before Christmas Petey's mother asked: " have your been a very good puppy?
" Oh, yes!" said Petey. I didn't frighten the cat.
"you didn't?" asked Petey's mother.
"Well,I just frightened her a little," said Petey. And I didn't chew any shoes.
" Not any?" said his mother.
"Just
a teeny-weeny chew", said petey. " And I remembered - well you have
been a good little dog. I will go out and get your a boy for Christmas.
But
when Petey's mother came back she looked very worried. "How world you
like a soft white rabbit with pink ears for Cristmas?" she said to
Petey.
