In the novel "Sometimes a Great Notion" by Ken Kesey, the protagonist reflects on the monotony of life, suggesting that each day feels similar and repetitive. This sentiment captures a feeling of frustration as time passes, transforming days into a dull routine. The imagery of soft, wet sandpaper conveys the sense of discomfort and irritation that comes with this sameness, highlighting the struggle against the inevitable passage of time.

The quote further emphasizes the relentless nature of time, which can erode experiences and memories much like the soft sandpaper that wears away surfaces. The connection to summer reinforces the idea of cyclical experiences that, while familiar, can also evoke a sense of stagnation. Kesey's exploration of these themes resonates widely, as many people grapple with the challenge of breaking free from the monotony of everyday life.
