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, almost always remembered - to bark when I wanted to go our. «All right,»said his mother. «I think you,ve been a good little dog.I will go our and get you a boy Christmas .» But when Petey's mother came back she looked very worried. "How world you like a soft white rabbit with pink ears for Christmas?" she said to Petey. "No, thanks," said Petey. "Don't you want a lovely canary?" "I'd like a boy," said Petey."How about some little fish?" said Petey's mother." I just want a boy," said Petey."Petey," said his mother at last,"there are no boys to be found." "No boys?" cried Petey. "Not one could I find. They're terribly short of boys this year". Petey thought he couldn't stand it if he didn't have a boy.
