This quote delves deeply into the complex human tendency to erect emotional barriers as a form of self-protection. The metaphor of "walls" represents the defenses each individual builds around their inner vulnerabilities. The interaction between the two characters highlights a mutual recognition that no one is immune to such protective fortifications. The woman's wall "glittering in a beauty he cannot stand" suggests that these defenses can appear alluring or even seductive but simultaneously cause discomfort or rejection in others. Her "beautiful clothes" and "pale face that laughs at everyone who smiles at her" evoke a striking image of contradictory emotions — the laughter acts as a shield, perhaps masking inner pain or isolation that is invisible to those around her.

This reflects the broader theme of human connection impeded by fear and mistrust. Both characters are isolated by their walls, which paradoxically creates a barrier not only to outside harm but also to intimacy and vulnerability. The tension lies in the simultaneous yearning to be understood and the fear of exposure. Ondaatje masterfully encapsulates the fragility of human relationships and the complex layers behind outward appearances, reminding us that beneath the surface of every person lies a protected self, fearful yet desperate for connection. Ultimately, this quote highlights the tragic beauty and loneliness inherent in human defensiveness.
