Here's a breakdown of how Bobby's appearance is described:
* Lack of attention: Bobby feels invisible even before his actual invisibility, implying that he doesn't stand out physically. He likely blends in with his surroundings, overlooked by his peers and adults.
* Insecurity about his body: While the novel doesn't explicitly detail Bobby's physical appearance, it does mention he's insecure about his weight and how it affects his physical capabilities. This suggests a self-consciousness about his body.
* Emphasis on his "invisibility": The novel focuses on Bobby's invisibility as a powerful metaphor for his feelings of alienation and isolation. It's more about the psychological impact of his condition rather than a detailed physical description.
* Changes in appearance: After becoming invisible, Bobby's physical appearance becomes irrelevant to the story. The focus shifts to the consequences of his invisibility on his emotions and relationships.
Overall, the lack of detailed physical descriptions in "Things Not Seen" is intentional. The focus is on Bobby's internal world and the struggles he faces as he navigates the challenges of being invisible, both literally and figuratively. This allows readers to connect with Bobby on a deeper emotional level, making his experiences more relatable and universal.
