"The Elves and the Shoemaker" was not an unfamiliar story to me, but there were parts I definitely didn't remember. (The elves were naked???) It's the story of elves helping out a poor, hardworking shoemaker during the night and pleasantly surprising to this modern reader, the shoemaker and his wife don't take advantage. Instead they are grateful and make clothes (not replacement clothes, as I'd remembered, just clothes) for the elves who are delighted but then leave forever. It's hard to comment on the Grimms' writing as these were folktales collected by the brothers and since translated into English so many times that it's kind of silly for me to even be suggesting they're the authors, but in any case, it's a charming story and I'm glad they were involved in its preservation.
Also, I never drew the connection to Dobby in Harry Potter books before now. Elves are apparently relieved of their duties when you give them clothes. I'm guessing there are some pretty cold elves in the North Pole.
