In "One Flew Over the Cuckoo's Nest" by Ken Kesey, the quote highlights the complexity of human emotions and experiences. It suggests that there is a depth in a person's expression that can be overwhelming. The idea is that when we confront another person’s true feelings and struggles, it often reveals more than we can comfortably handle, showing the raw vulnerability that lies beneath the surface.

This reflection on human connection emphasizes both the beauty and the burden of truly understanding one another. It implies that looking deeply into someone’s face can unveil their innermost fears and pains, making direct interpersonal interactions daunting. The weight of this truth often leads to a desire to shield oneself from such profound emotional exposure.
