Heartwarming / A Hat Full of Sky

• Tiffany dancing with the bees becomes a Fridge Moment of Heartwarming if you consider that she's actually dancing with Granny Weatherwax. Stern, stolid, life-pared-to-the-core Esme, who'd never in a million years dare engage in such a carefree activity where anyone could see her, actually got to let her hair down and enjoy a playful moment with someone who understands what it's like to be the best witch of your generation.
• Yet another Fridge Moment of Heartwarming with those two is Granny giving Tiffany her hat. She said it was because Tiffany was a true witch and no witch should be without one, but the only reason Granny isn't the last person to believe that fashion is important to witchcraft is because she doesn't believe it at all. There's another, subtler reason she did it; to make Tiffany's argument respect her. Keep in mind that though Tiffany was very badass literally talking an Eldritch Abomination to death, nobody actually saw what happened from the outside. It would have been just like Fairyland where no-one would believe her experience, and she'd come off as loony. They didn't respect her, but they did (oh, how they did) respect Granny, so when Granny described what happened, called Tiffany a true witch, then give her the symbol of witchhood itself, of course the argument would revere her the same way they revered Granny, and who cares that all they saw was a big ice wall. Granny gave her two gifts in one; headgear and the single-handed prevention of Tiffany being a social outcast for the rest of her childhood.
• The Feegles replacing Mr. Weavall's stolen savings with some of the treasure from their mound. He's so overjoyed with his newfound wealth that he proposes to the widow down the lane.
• This exchange regarding Petulia.
  Granny Weatherwax: Friend of yours?
  Tiffany: If she is, I don't deserve it.
  Granny Weatherwax: Sometimes we get what we don't deserve.
• The very existence of this structured and populous regime of witch recruitment and training is heartwarming. In Witches Abroad, Magrat was the youngest witch in all the Ramtops in her mid-twenties, and their numbers were dwindling as the remaining witches aged and died. All of them could barely get together a pot luck with too much potato salad. There was talk about witchcraft going away entirely. It's heartwarming that under Weatherwax's leadership, there is not only a plethora of apprentices and young witches, but enough witches to hold an annual carnival.
