What is the theme in Oh Dad, Poor Dad, Momma's Hung You in the Closet and I'm Feelin' So Sad by Arthur L. Kopit?

Another theme in the book is obedience. Jonathan Rosepettle's obsessive fears from his total obedience to his mother and her tyrannical control of him. He is a devastating caricature of the dutiful son, locked away from the outside world that his mother believes would corrupt him and turn him into another despicable man. His repressed hatred for her emasculating authority starts to well up in him, but he is so afraid of her that the most he can manage is an attack on her pets, surrogate targets that in the most primitive sense embody what she herself is: a man-eating carnivore.
