I was having trouble with a male neighbor named Miyashita who lived in the apartment next door, and it was beginning to take a serious toll on my household. My wife had long been frustrated with this neighbor due to various behavioral issues—smoking in shared spaces and repeated violations of apartment etiquette. Being a peaceful, easygoing, and passive person by nature, I always dismissed her concerns with a light laugh, telling her not to worry so much. However, my wife was postpartum, and her breast milk production was extremely high, squirting out abundantly. Under these conditions, the neighbor’s constant misconduct caused her immense stress.
