Final answer:
Matt's response to Danny's concerns about cleanliness is a textbook example of defensive communication, where Matt reacts to protect his self-esteem rather than solve the problem.
Step-by-step explanation:
The scenario with Danny and Matt regarding different definitions of 'clean' illustrates a common interpersonal conflict. Matt's defensive response when Danny tries to discuss the issue may be categorized by the authors of a textbook as a form of defensive communication.
This is characterized by reactions that aim to protect one's self-esteem rather than addressing the conflict constructively. Matt perceives Danny's attempts to communicate about cleanliness as an attack on his character, prompting him to lash out and divert the conversation away from the actual issue.
