In the excerpt from "Pale Fire" by Vladimir Nabokov, the narrator expresses a common sense of anxiety before visiting a doctor. This feeling is relatable, as many people experience trepidation about medical appointments. To alleviate this nervousness, the narrator decides to purchase something calming on the way, hoping it will help maintain a steady pulse, which might otherwise be misinterpreted by an unwary medical practitioner.

This passage highlights the interplay between human emotions and the perception of health. The narrator is aware of how anxiety can affect physiological responses and, by preparing in advance with a soothing purchase, seeks to navigate the uncertainties of a doctor's examination. This introspection reflects a deeper commentary on how individuals often manage their fears, especially when faced with authority figures in the medical field.
