In Marjane Satrapi's "The Complete Persepolis," the act of smoking a cigarette signifies a pivotal moment in her life, marking the transition from childhood to adulthood. This moment embodies a desire for independence and a break from the innocence of youth. The quote reflects the complexity of growing up, where taking on adult behaviors comes with both freedom and the loss of childhood simplicity.

The cigarette serves as a symbol of maturation, capturing the protagonist's internal conflict about embracing a more complex identity. Satrapi's narrative illustrates the challenges of adolescence against the backdrop of political upheaval, highlighting how personal milestones are intertwined with broader societal changes. The transition from child to adult is both liberating and fraught with new responsibilities.
