Why does Jack insist that it was the wizard that was hit and not the mother?

Explanation

Jack has the typical parental attitude. He is of the opinion that the parents know what is best for their children. He asserts the parental authority time and again to quieten Jo
and stifle her objections and amendments to the story of the foul smelling Skunk related by him.
He defends the attitude of Roger Skunk's mother. She does not approve of the unnatural, unskunk- like smell that Roger has. She calls the sweet smell of the roses an awful smell. Earlier the little skunk smelled the way a little skunk should. She wants the natural characteristic,the foul smell,restored. He says that she knew what was right. Secondly, the little skunk loved his mommy more than he loved all the other animals. That is why, he took his mommy to the wizard. She hit the wizard and forced him to change the smell of roses to his earlier bad odour. He insisted on this ending to emphasise the concern of the parents for children and their role in bringing them up on proper lines.
