In the book "Proof" by Dick Francis, the character reflects on the repetitive nature of conversations with Mrs. Palis­sey. They often revisit the same topics, suggesting a routine that may lack excitement or depth. This monotony can be indicative of their relationship dynamics, where important discussions seem to circle back to familiar themes without progression.

This repetition might reflect both characters' comfort with each other as well as a possible avoidance of more challenging subjects. Ultimately, it highlights how relationships can settle into familiar patterns, sometimes at the expense of exploring new ideas or addressing unresolved issues.
