How to Handle Grown-Ups is a humorous, non-fiction guide written for children, offering tongue-in-cheek advice on how to manage, manipulate, and generally survive the often-baffling behavior of adults (parents, teachers, etc.). The guide is written from a child's conspiratorial point of view, addressing common grievances like chores, homework, and unreasonable rules. The humor stems from the exaggeration of adult eccentricities and the idea of children having secret control over them. The book is a lighthearted, engaging read that validates a child’s perspective while providing entertainment through its witty, anarchic tone.
