Of course, Granny Weatherwax made a great play of her independence and self-reliance.

It was like hermits. There was no point freezing your nadgers off on top of some mountain while communicating with the Infinite unless you could rely on a lot of impressionable young women to come along occasionally and say ‘Gosh’.”
““Blessings be on this house,” Granny said, perfunctorily. It was always a good opening remark for a witch. It concentrated people’s minds on what other things might be on this house.””—Terry Pratchett - Witches Abroad
