The quote reflects on the passage of time and how each day slips away, much like its predecessors. This notion evokes feelings of nostalgia and the inevitability of change, as each day seems to take with it experiences, emotions, and moments that can never be reclaimed. The imagery suggests that time is a continuous flow, where every day contributes to the larger narrative of life.

Margaret Atwood’s "The Robber Bride" uses this idea to emphasize the transient nature of existence. Each day’s departure signifies the accumulation of memories and experiences, which can alter one's perspective on life. It serves as a poignant reminder to cherish each moment, as the days are fleeting and carry away pieces of our lives as they pass into the past.
