Ok but so many fairytales are about the kindness of strangers? Like the huntsman in Snow White and the woodsman in Red Riding Hood and the prince and the nomads and the little old women in The Snow Queen (Gerda survives solely and only from the kindness of strangers, no other reason) and the countless old women who help princes along their paths? Anyway what I'm trying to say is that fairytales are often meant to be cautionary, but even as they warn children about bad behaviour, they also tell them that there is warmth and protection even from strangers, and the non-cautionary ones are so full of strange kindnesses, of the idea that if you are good and polite and just then the world will be good and kind and just back. And it's just... This is what people have fundamentally believed for centuries, this is what, more than anything, they have wanted to tell their children. That when you are out and lost and cold in the world, you are not alone.
