Six months before the trivia night, Madeline Martha Mackenzie turns forty and drives her five-year-old daughter, Chloe, to Pirriwee Public for kindergarten orientation. Madeline is determined to enjoy the day with coffee, cake, birthday attention, and lunch plans, but the milestone makes her reflect uneasily on age, death, and how differently the world values youth and middle age.

On the way to school, Madeline thinks about Chloe’s confidence, her son Fred’s school routine, and the competitive parents already orbiting Pirriwee Public, including Renata and Harper. She also anticipates meeting Celeste, whose twin boys will attend orientation. The morning appears bright and celebratory, reinforced by Madeline’s new stilettos and Ed’s affectionate declaration of the “Festival of Madeline.”

Madeline’s mood shifts when she notices a young woman driving a crowded blue Mitsubishi while using a mobile phone. Alarmed by the danger of texting while driving, Madeline lectures Chloe about road safety, only for Chloe to point out Madeline’s own past hypocrisy. Their conversation reveals Madeline’s dramatic, comic parenting style and Chloe’s sharp, precocious manner.

At a red light, Madeline honks at the young driver and demands that the girl put down the phone. When the girl responds rudely, Madeline stops her own car, gets out, confronts the driver, grabs the phone, and tosses it to the passenger. The teenagers laugh at Madeline, but Madeline feels energized by the confrontation and returns toward her SUV.

As Madeline hurries back in her new stilettos, her ankle twists badly and she falls. The chapter closes by framing this awkward injury as the likely beginning of the larger story, connecting Madeline’s impulsive intervention and her birthday morning to the chain of events that will lead toward the trivia-night tragedy.
