The quote from Margaret Atwood's "The Blind Assassin" captures a profound sense of unpredictability and the relentless passage of time. The comparison to trains suggests a journey that is perpetually in motion, yet also highlights the unavoidable delays and irregular arrivals in life. Just like trains that adhere to schedules yet often fall short, the woman referenced embodies the idea of continual departures, implying a dissatisfaction with the present and an ongoing search for something more fulfilling or meaningful.

This metaphor serves as a poignant reflection on human experiences and relationships. The notion that someone is "never on time" suggests a struggle with commitment or the fear of stagnation, while "always departing" conveys a sense of longing and the inevitability of change. In literature, such imagery evokes rich emotions about the nature of existence and connections, illustrating how individuals navigate their paths through time, often marked by transitions and unfulfilled desires.
