The quote reflects a character who tends to perceive a gloomy atmosphere in situations, especially during moments of transition, such as when daylight fades into evening. This suggests a tendency toward pessimism or a melodramatic outlook, where the character’s mood darkens as shadows lengthen, emphasizing his sensitivity to changes in his environment.

Additionally, the mention of it being "too early for a cocktail" adds a humorous twist, hinting at the character's reliance on drinks to lighten his mood. The juxtaposition of serious feelings with the lighthearted context of cocktails points to the character's struggle between outlook and circumstance, illustrating Wodehouse's comedic style in "Heavy Weather."
