In lines 74-83, the author discusses people's capacity to accept change. Why does she introduce these ideas immediately before "falling out"?

Hello. You have not specified the text to which this question refers, which makes it impossible for this question to be answered accurately. However, we can consider that the event in which the character "falling out" represents a major change in her life, for this reason, to discourage people's ability to accept changes before that event, presages the character's resilience and her ability to endure the difficulties that the changes in her life would cause, thus proving the author's argument about the capacity to support changes.
