In Richard Brautigan's novel "In Watermelon Sugar," the narrator expresses their feelings about a particular note they encountered. The note did not evoke any positive emotions, leading the narrator to discard it without hesitation. This action signifies a broader theme of rejecting unpleasant memories or experiences, emphasizing the desire to move on without looking back.

By throwing away the note, the narrator symbolizes a decisive break from the past. The mention of time suggests that even the passage of time cannot recover what has been intentionally forgotten. This reflects a profound understanding of the weight of memories and the importance of choosing what to retain in one's life.
