“ Gytha Ogg, you wouldn’t be a witch if you couldn’t jump to conclusions, right?” Nanny nodded. “Oh, yes.” There was no shame in it. Sometimes there wasn’t time to do anything else but take a flying leap. Sometimes you had to trust to experience and intuition and general awareness and take a running jump. Nanny herself could clear quite a tall conclusion from a standing start. ”
