In Vladimir Nabokov's "Lolita," the protagonist expresses a profound sense of vulnerability, likening his life to a glass house filled with light. This metaphor illustrates a constant awareness of being observed, suggesting that the character feels his private experiences are laid bare for the world to see. The imagery evokes the idea that even the most mundane aspects of his life become spectacles for others, highlighting a sense of exposure and lack of control.

The quote captures a tension between desire for privacy and the inevitable scrutiny that comes with it. The notion of a "thin-lipped parchment face" represents an invasive observer, hinting at the moral complexities and voyeuristic tendencies present in society. This awareness of being watched not only affects the character's sense of self but also reflects the broader themes of obsession and the human condition present throughout the novel.
