It was four in the afternoon. After having tea in the living room, Jim got up and walked to the window. He looked out of the window and saw two men in his neighbour’s garden. The men were carrying a big color TV. They were carrying the TV to a car.
Jim opened his window and said to the men, “Hey, guys! Are you good at mending TVs?” “Yes,” The men looked at him and smiled. “Are you going to mend that TV?” asked Jim. “Of course,” answered the men.” My TV is broken. Can you take it and mend it for me ?” “Sure,” the men said happily.
In no time, Jim carried his colour TV downstairs and gave it to the men. The men put the two TVs into the car and drove it away. With a smile on his face, Jim stood there and saw the car leaving. But to his surprise, he never saw it coming back again.
