In "Summer Lightning" by P.G. Wodehouse, the characters engage in a light-hearted conversation where one character expresses confidence in his belief, prompting another to recall a previous discussion. However, Lord Emsworth, known for his forgetfulness, admits that he has forgotten the details of what was said. This exchange highlights not only Emsworth's absent-minded nature but also the humor Wodehouse infuses into his dialogue.

The interaction serves to illustrate the comedic tension between the characters, showcasing their differing memory abilities and the ensuing misunderstandings. Lord Emsworth's forgetful disposition adds to the charm of his character and sets the stage for further humorous situations throughout the narrative. Wodehouse's wit shines through as he captures the essence of human interactions marked by forgetfulness and the lighthearted banter that arises from it.
