In the book "Heartbreaker" by Julie Garwood, a significant quote states, "You kill a cockroach, Pete. You don't domesticate him." This line metaphorically contrasts the ideas of dealing with undesirable situations versus attempting to control or change them. The imagery of a cockroach, often seen as a pest, emphasizes that some things are meant to be eliminated rather than manipulated. This sentiment can reflect broader themes in the story, such as the challenges of relationships and the nature of trust. Just like one must take decisive action against a cockroach, characters in the narrative may need to confront their problems directly instead of allowing harmful influences to linger.

You kill a cockroach, Pete. You don't domesticate him.

In this quote from Heartbreaker by Julie Garwood, the idea of eliminating problems instead of trying to control them is highlighted.
