In "Psmith in the City," Mike finds it perplexing that Psmith enjoys immersing himself in environments that do not align with his own background. While Mike, typical of his peers, feels most comfortable among friends of his own age and social class, Psmith appears disinterested in his contemporaries. This contrast highlights a key difference in their characters; Mike seeks familiarity, while Psmith actively seeks out experiences and conversations outside his immediate social circle.

Psmith's preference for engaging with people from different worlds suggests a desire for exploration and a deeper understanding of life beyond his own experiences. This tendency to embrace diversity of thought and interactions sets him apart from Mike, who embodies a more conventional approach to socializing. Psmith's quest for novelty and connection reflects a broader theme of individuality and the human experience, showcasing how different personalities navigate their social landscapes.
