"Nanny rather liked the theatrical world. It was its own kind of magic. That was why Esme disliked it, she reckoned. It was the magic of illusions and misdirection and foolery, and that was fine by Nanny Ogg, because you couldn't be married three times without a little fooling. But it was just close enough to Granny's own kind of magic to make Granny uneasy. (p. 161)"
