How did Anne turn the table …

Mr Keesing remained annoyed with Anne for talking in the class. As a punishment he gave her extra homework. Anne was to write an essay on ‘ A Chatterbox’,and then on ‘An incorrigible Chatterbox’. Anne wrote the essays and Mr Keesing like them. But she didn't give up her habit of talking in the class. Now Mr Keesing asked her to write a very unusual essay. The title of the essay was : “Quack, Quack, Quack,” said Mrs. Chatterbox. In fact Mr Keesing had intended to play a joke on Anne. But Anne wrote the essay in such a way that it became a joke on Mr Keesing himself. She wrote that in the form of a verse. It told the story of a mother duck and a father swan. The father bites his three ducklings to death because they quacked too much. The father in the poem is clearly Mr Keesing and the ducklings are the children of his class. Luckily Mr Keesing took the joke the right way. He liked the poem and read it  to several classes. He stopped giving Anne any extra homework. He allowed her to talk in the class. He even started making jokes with the children.
