The author, Jonathan Safran Foer, shares a personal and symbolic gesture of having the words "YES" and "NO" tattooed on his palms. This choice represents the dualities of life, where both affirmations and rejections are essential to existence. He reflects on how these tattoos contribute to his experience of life, allowing him to navigate the complexities and contradictions of reality.

Foer suggests that the act of rubbing his hands together in winter brings warmth, highlighting the interplay between acceptance and refusal. When he claps his hands, he expresses gratitude, and he views each book as a reflection of the balance between these two forces. In this way, he conveys how literature encapsulates the human experience of balancing choices and values.
