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?

Absurdity is a theme in this book. As Kopit indicated in the subtitle of Oh Dad, Poor Dad, Mamma's Hung You in the Closet and I'm Feelin' So Sad, he was influenced by the "bastard French tradition," meaning the plays of the avant garde Parisian dramatists, some of whom, like Beckett and Ionesco, were expatriates living in France. Elements of the absurd include highly exaggerated, dysfunctional familial relationships, which is most notably present in the play in the maltreatment of Jonathan by his mother, whose overprotectiveness is simply destructive.
