The quote reflects on the fleeting nature of pain and remembrance. It suggests that once the suffering associated with a person or experience fades away, it's challenging to retain the memories of that pain. Instead, what lingers is merely a shadow of the past, unable to impact our thoughts or physical presence. This implies a disconnection from the intense emotions that once existed.

Furthermore, the passage emphasizes that while pain might leave an indelible mark, it often remains hidden from conscious perception. The scars of our experiences may not be visible to others or even to ourselves, highlighting how deeply personal trauma can influence us without leaving a tangible trace. Through Atwood's words, we are reminded of the complexity of memory and the subtle ways it shapes our identities.
