The quote from Margaret Atwood's "The Blind Assassin" presents a philosophical inquiry into the nature of existence. It questions the significance of the two fundamental aspects of breathing – inhalation and exhalation. This contemplation invites the reader to reflect on the duality of life and the interconnectedness of these actions, suggesting that both are essential yet distinct components of the human experience.

In a broader sense, the statement can symbolize various life processes, including creation and destruction, beginnings and endings. It challenges us to consider which aspect holds greater meaning or value. Through this lens, Atwood encourages introspection about our choices and the ways in which we engage with life itself.
