An intelligent parrot

A man had a parrot. It was a very beautiful bird and every day the man talked to it.
"Pretty Parrot," he said. "You are a pretty Polly".
"Pretty Parrot" the parrot said. "You are a pretty Polly".
Everyday the man spoke new words to the parrot. "Hallo" he said and "Good bye".
One day the parrot was not in its cage. It was flying about the room. The man came into the room and saw the parrot.
"What are you doing?" he said.
"What are you doing?" the parrot said.

The man laughed. Then he went out to visit his friends.
That evening a thief came to the house. He walked round the house and looked into the windows. There was no one at home. The thief broke open the door and entered the house. First he went into the sitting-room. In the sitting-room he found some books and papers. He put them into a bag. Then he went into the bedroom. In the bedroom he found a gold watch and some money. He put these into the bag, too. He stole many things from the house and put them into his bag.
The bag was soon full. The thief put it over his shoulder and walked to the door. He opened the door and looked out. There was no one there.
"What are you doing?" a voice said.
The thief jumped high into the air and dropped his bag. Then ran out of the house and down the road.
"What are you doing?" the voice said again. "Pretty Polly. Hallo. Good bye. What are you doing?"
