In Margaret Atwood's novel "Oryx and Crake," the protagonist experiences unexpected moments of joy that seem to arise without cause. These instances of irrational happiness appear out of the blue and contribute to the complexity of his emotional state, suggesting that he grapples with deeper issues beneath the surface.

The character humorously speculates that such feelings might be due to a vitamin deficiency, revealing a sense of confusion about his happiness. This notion underscores the ironic and often absurd nature of human emotions, particularly in a world filled with challenges and dystopian elements.
