Chapters 17-36 Analysis

In this section of Dear Debbie, the chapters containing discarded column drafts begin to speak directly to Debbie’s personal life, deepening the text’s exploration of The Danger of Secrecy in Relationships. As the line between Debbie’s personal life and her imagination begins to blur, the violence of the drafts begins to leak into her real life. Chapter 24 contains a letter from a woman complaining that her husband’s snoring makes sleep impossible. Debbie’s draft suggests that the letter writer encourage “regular exercise” (115) and “weight loss” (115) for her husband to solve the problem. This advice closely mirrors the experience of Debbie’s husband Cooper, who has been able to “get back in shape” (84) after many years as a result of visiting the gym “at least three times per week” (84). The resonance between Debbie’s advice and her husband’s experience suggests that Debbie draws from her own life while drafting her letters.


However, Debbie’s draft letters always end in violence, and the novel suggests that Debbie might begin acting on these violent impulses. The draft in Chapter 24 ends with Debbie suggesting that the letter writer kill her husband if losing weight doesn’t stop his snoring. The very next chapter begins with Debbie waking to the sound of Cooper “snoring softly” (116) in bed beside her. The revelation that Debbie has drugged her husband with opium harvested from her garden echoes the violence of Debbie’s letter in the previous chapter.


The resonances between the draft and Debbie’s relationship with her own husband suggest that her violent fantasies are close to becoming a reality. This pattern repeats in Chapter 30, which contains a letter from a woman who “can’t stand” (141) her daughter’s boyfriend. The woman’s description of the boyfriend’s “attitude problem” (141) closely echoes Debbie’s opinion of Lexi’s boyfriend Zane, whom she describes as “surly as they come” (16). Debbie’s suggestion that the letter writer cut the boyfriend’s break lines foreshadows Debbie’s later treatment of Zane, when she will arrange for his car crash into the school.


In this section of the novel, it is revealed that Debbie’s friend Harley believes she is having an affair with her husband Cooper. However, there are suggestions from the beginning that Harley and Cooper’s relationship is not what it seems. The chapters narrated by Cooper suggest that he is not only in love with his wife but actively sexually attracted to her. Despite Debbie’s self-deprecating description of her body, Cooper insists that “she looks great in everything” and that she is “a woman I’d never be able to get out of my head” (94). He describes meeting her as “a bolt of lightning” (94), and insists that his feelings have not changed. Cooper’s narration suggests that he is dedicated to his wife and still finds her sexually attractive.


In Harley’s chapters, however, the man who presents himself as “Cooper” offers an entirely different perspective. He tells Harley that he and Debbie “are like strangers who are forced to live together” (101) and that he has been “sleeping in the guest room for years” (102). This suggests that Cooper is not sexually or emotionally connected to his wife. As a result, Harley believes that “he doesn’t love Debbie anymore” (102), and she begins to orchestrate opportunities for Debbie to discover the affair. The disconnect between Cooper’s narration and Harley’s suggests that something in their relationship is not what it seems. It will later be revealed that Harley’s “Cooper” is not Cooper at all, but his coworker Jesse—Debbie’s unsettled reaction to finding the man’s shirt in Harley’s home is therefore not because she recognizes it as Cooper’s, but because she recognizes Jesse’s scent. Harley’s assumptions that “Cooper” is who he says he is and Debbie’s reaction to the shirt thus create misdirection in the narrative, attempting to deceive the reader into misinterpreting what is really going on.


The development of the character of Coach Pike in this section reflects the novel’s thematic interest in Misogyny and Attempts to Control Women’s Bodies. Coach Pike feels like his role as coach entitles him to control the bodies of the teenage girls on his soccer team. When confronted about asking Izzy to lose weight, Pike explains that “nobody wants to watch a bunch of chubby girls running around the soccer field” (91) and that the sight of overweight players “isn’t going to make the crowd happy” (91). Pike’s explanation suggests that he believes the primary job of the soccer players is to be attractive to spectators. This perspective reflects his belief that society is entitled to control women’s bodies from a young age. Pike’s insistence on skinny soccer players is hypocritical given the fact that he himself is “in poor shape” (89), with his coaching uniform barely stretching “over the folds of his belly” (89). Pike’s physical appearance highlights that he does not bother to conform to his own idealized standards, suggesting that he is interested in control rather than pure athleticism.
