In the book "CHOOSE" by Philip K. Dick, the narrative highlights the complexities of dealing with grief and the human tendency to seek humor in difficult situations. A poignant exchange occurs between the narrator and a doctor, where the doctor tries to lighten the mood by stating that there are worse diseases than cancer. This dark humor reflects the coping mechanisms people employ when faced with dire circumstances.

The laughter shared between them, despite the heavy topic, emphasizes the importance of finding moments of levity amidst sorrow. It illustrates how humor can serve as a temporary relief from overwhelming grief, allowing individuals to navigate their emotional turmoil, even if only for a brief moment.
