Who is Daisy in the novel, Good Material?

Daisy is a woman Andy broke up with in the past and their brief encounter makes Andy confront the consequences of his actions and begin to understand the pain he might have caused. When Andy unexpectedly bumps into Daisy, he believes she is upset by the encounter, which he interprets as regret for their breakup. This encounter allows Andy to gain some perspective on his own experiences, particularly his breakup with Jen. However, Daisy's reaction to Andy's assumptions reveals his unreliability as a narrator. She is offended and annoyed by Andy's belief that he could discern her feelings so easily, when in fact she had not had a strong emotional reaction to their meeting at all. This interaction underscores Andy's tendency to project his own emotions and assumptions onto others, highlighting his limited understanding and empathy.
