In a condominium where a couple has lived for two years without having children, there was a problematic neighbor. This neighbor repeatedly engaged in smoking in shared spaces and other unpleasant behaviors, causing constant stress for the wife, who served as an officer in the neighborhood association's women's division. I, a pacifist who strictly adheres to vegetarianism, always comforted my wife by telling her not to make too much of a fuss to ease her frustration. But one day, this approach led to a major problem.
