The character's disdain for constipation highlights her strong aversions, placing it alongside other societal issues she deeply loathes, such as domestic violence and intolerant religious views. This comparison illustrates how seriously she takes personal discomfort as well as larger moral issues, suggesting a profound sense of injustice and an eagerness to confront life's burdens.
By equating constipation with such grave social problems, the author, Haruki Murakami, invites readers to consider the weight of even minor personal struggles against the backdrop of serious ethical dilemmas. It underscores a theme of interconnectedness between personal and societal challenges in the narrative, reflecting complex human emotions.
