P.G. Wodehouse humorously conveys the protective instinct some may feel toward friends about to make significant life choices, such as marriage. The narrator compares this urge to that of a dog trying to save its master from peril, suggesting a deep sense of loyalty and concern for well-being, especially in regards to the character Stilton.
This analogy emphasizes the absurdity and gravity of the situation. Just as a dog is instinctively driven to avert danger, the narrator experiences a strong desire to intervene before Stilton proceeds with a potentially disastrous decision. Wodehouse's writing reflects the complex emotions tied to friendship and the often comedic challenges faced in navigating personal relationships.
