I have a friend who’s a chumra queen. I think she keeps every chumra anyone ever came up with, and a few she made up herself.
She frequently tells me I’m doing something wrong. I usually just ignore her. Once in a while, I’ll ask my rav, and he confirms that she’s wrong. (Not wrong about keeping a chumra, wrong about what the halacha is, and trying to impose her chumras on the rest of the world.)
