In her poem, Margaret Atwood reflects on the transient nature of existence and human connections. She expresses a sense of impermanence, suggesting that while words can create temporary connections, they eventually fade away, just like people do. The idea that one will "flicker" in memories and in the memories of others captures the fleeting essence of life and relationships.
Additionally, Atwood conveys a profound sense of separation and loss through the imagery of letters never received and encounters that are ultimately unfulfilling. This highlights the deep emotional impact of unfulfilled communication and the painful realization that even reunions can feel incomplete, leaving us with a sense of longing and nostalgia for what has been lost.
