Phoebe’s laminated checklist, which structures each item as a pass-fail task, converts emotional vulnerability into a project she believes she can manage like a spreadsheet, highlighting The Arbitrary Nature of Timelines for Social Milestones. Phoebe frames her checklist as a logical solution to an overwhelming problem: “why not make a list for the one thing I need to do more than anything else?” (31). Faced with the upcoming deadline of her 30th birthday, she channels her obsessive-compulsive tendencies into a goal-oriented plan to achieve a romantic life that she perceives as socially normal, course-correcting the ways she feels she fails to measure up.

The checklist becomes the primary engine for the plot, pushing her toward manufactured encounters: flirting with Rob, a teacher she pursues as a list task, or complimenting a stranger’s orthopedic boot. As Phoebe tells her friends, “This will be a list of tasks […] The more of these tasks I do, the higher the chances are of me having sex in the next thirty days” (32). However, rather than relieving anxiety, the pressure to tick items off transforms connection into a series of performance reviews. The list hardens into a barrier to intimacy, reinforcing her feelings of inadequacy until the moment she abandons it entirely and allows a relationship to develop without a deadline attached.

The recurring motif of crossword puzzles highlights the genuine connection and emotional intimacy between Matthew and Phoebe throughout the novel, offering a healthy alternative to Phoebe’s anxiety-fueled quest to achieve sexual milestones. Where her checklist demands manufactured, high-pressure scenarios, the crosswords shared between Phoebe and Matthew create a low-stakes space for their relationship to develop without a schedule. Their daily ritual of swapping scores and celebrating each other’s results builds a foundation of mutual respect, wit, and shared interest.

Their sustained, non-physical intimacy lets Phoebe connect with Matthew without triggering the panic associated with her fear of physical closeness. The depth of their bond surfaces when Matthew texts her, “Is it sad that swapping scores with you is the best part of my day” (85). His admission marks how their connection operates on an emotional plane that her checklist never accounts for. By sustaining that daily exchange without any item to cross off, the crosswords directly challenge the logic of her self-imposed quest, demonstrating that meaningful connection does not adhere to a forced schedule and often grows in quiet, shared moments rather than calculated milestones.
