The book "The Wanderer" by Robyn Carr features a character who humorously underestimates another's sense of humor. The quote "Isn't he cute? That he thinks he has a sense of humour?" suggests a light-hearted mockery, indicating that one character finds amusement in another's attempt at humor. This implies a playful dynamic between the characters, where one is not quite able to grasp the situation, leading to an endearing evaluation from the other.

This interaction highlights the themes of connection and misunderstanding among individuals, emphasizing how humor can sometimes create barriers or highlight differences in perception. The narrative structure of "The Wanderer" likely explores these dynamics further, revealing the complexities of relationships through witty and relatable dialogue.
