In Richard Russo's novel "Straight Man," the quote raises an intriguing question about the essence of good fiction. It suggests that effective storytelling may hinge more on personal perspectives and individual experiences than on broader themes or universal truths. This idea emphasizes the importance of character and viewpoint, suggesting that how a story is told can often be just as significant as the story itself.

The contrast between "the air we breathe" and "the nose we breathe it through" invites readers to reflect on the subjective nature of reality in storytelling. It implies that a well-crafted narrative can reveal deeper truths when focused on the unique experiences of characters, making fiction relatable and resonant on a personal level. Ultimately, the quote highlights the balance between external influences and personal interpretation in creating engaging literature.
