In P.G. Wodehouse's "Carry On, Jeeves," the notion of friendship is explored through a humorous lens. The quote highlights the idea that while friendship is important, it has boundaries that shouldn't be crossed. This serves as a reminder that loyalty and support have their limits, suggesting that even the strongest friendships may face challenges when personal interests come into conflict.

This perspective reflects the complexities of human relationships, where mutual support must be balanced with individual needs and values. Wodehouse uses wit to convey that while friends can rely on each other, there are situations where one must draw a line to maintain personal integrity and well-being.
