Ow. Most people just get dust in their eyes.
Hmm... Chapter 122, Watermelon Day. It's similar to my other favorites by starting with a mundane scene but gradually becoming more emotional. Even though the conversation appears to remain colloquial, there's so much being said without being explicitly stated. The words are simple, nothing preachy, fancy, or too idealistic, but they're somehow able to make the reader feel the gravity of the situation: the passing of an era and the passing on of a legacy.
