In "The Art of Discworld", Pratchett says, "I've always suspected that Nanny is, deep down, the most powerful of the witches and part of her charm lies in the way she prevents people from finding this out." Indeed, incurring Nanny's wrath is suggested to be much more dangerous "because" of her reflexively kind personality. In Pratchett's short story "The Sea and Little Fishes" Nanny Ogg also identifies herself, and the Ogg family as a whole, as having immense natural magical talent, but as less willing to work it as hard as Weatherwaxes do.
