In Sinclair Lewis's "Free Air," the phrase "You bet" conveys agreement or affirmation, akin to saying "yes" in a more casual manner. Additionally, the author uses a complex expression to suggest that while one may perceive something uniquely, there may still be a kernel of truth in that viewpoint. This reflects the nuanced nature of human opinions and perceptions.
Furthermore, Lewis includes a statement that acknowledges deceit, implying a recognition of dishonesty while choosing not to confront it. This interplay of expressions illustrates the multifaceted communication between characters, revealing underlying tensions and societal norms of the time.
