The quote reflects a moment of frustration where the speaker is being consoled by someone who trivializes their feelings. The reassurance that everyone forgets small things seems inadequate, suggesting that the speaker's emotional turmoil is tied to larger worries. This raises a deeper concern about the significance of memories and the potential loss of bigger, more important aspects of life.
The underlying question posed by the speaker contemplates the fragility of memory and existence. If minor details can fade away, there is a fear that more pivotal elements may also be at risk. This reflects a universal anxiety about the permanence of our experiences and the implications of forgetting, invoking thoughts about identity and the essence of our lives.
