Although I live in my own house, I am still affected by crazy neighbors that aren't JW's. To keep "the peace" I had to remove a small pile of dead grass, why? Because the crazy husband and wife convinced themselves that it was the cause of the "awful" smell that kept them from sitting on their porch. In reality, they had their garbage container there for a few days previously that reeked. But it couldn't be that, nooooooooo. The husband did things for revenge like running his compressor early or late at night before I found out the reason.
I threw the pile of grass into the garbage - it smelled like hay - and they magically could sit on their porch.
So crazy comes in all sizes and that is what that "sister" is. Lisarose has it right, ultra righteousness at play here.
