Charlie was a special boy. When he was little, he had accident, which meant he couldn't walk. But that had never been a problem for him. He had always been happy to be able to grow and become an (old) boy. People called Cheerful Charlie because of his happy nature and kindness to others.
A young boy, known as Waterworks, was a real cry boy. No matter Charlie said to him, Waterworks would always find some (reason) to be sad. But Cheerful Charlie didn't give up. He spent some time with Waterworks, trying (encourage) him and cheer him up.
One day when the two boys (walk) together in the street, someone dropped a cake from a window above, and it (land) right on Charlie's head. The two boys were afraid, and although Waterworks was just to cry, he thought Charlie's happy words and finally said, "Wow, Charlie, what a funny face you have!"
With these words, Waterworks (feel) so good, and finally understood why Charlie was always so happy and cheerful.
