Thank you for the lovely description.

It brought to mind Daniel Kahneman's research. How people perceive an unpleasant experience is determined by how bad the experience was at the conclusion rather than the average of the entire experience.

This psychological phenomenon is known as the Peak-End Rule, discovered and formalized in the 1990s by Daniel Kahneman, Donald Redelmeier, and Barbara Fredrickson.

The core finding is that retrospective evaluations of an unpleasant experience are not an integral (mathematical sum or average) of pain over time. Instead, the retrospective evaluation is almost entirely predicted by a simple heuristic: the average of the peak intensity of pain and the pain level at the very end. Furthermore, the actual duration of the episode has virtually no impact on retrospective memory—a finding Kahneman termed duration neglect.
