What is the theme in The Man Who Turned Into a Stick by Kobo Abe?

Alienation is a theme that runs through most of Abe's work. In The Man Who Turned into a Stick, alienation is represented as Hippie Girl and Hippie Boy, the younger generation. Their alienation is specifically expressed by Hippie Girl when she declares that there is a generation gap between her and Hippie Boy and the man and woman from hell. Hippie Girl also delivers the line: "We're alienated."
