In "Summer Lightning" by P.G. Wodehouse, the tension between Lady Constance and her brother is palpable. At a moment of rising irritation, her lips tighten, suggesting she is on the verge of losing her composure. The scene is charged with the possibility of her throwing a silver ink-pot at him, highlighting both her frustration and the playful chaos that often characterizes Wodehouse's narratives.

This moment encapsulates the humorous and unpredictable dynamics of family relationships. The idea of a beautiful ink-pot being hurled in anger adds a layer of absurdity, typical of Wodehouse’s style, where conflict is sketched with wit and a sense of the ridiculous, showcasing the interplay of emotions in comedic situations.
