Since I wrote this post in 2016, my copy of Tarzan at the Earth’s Core has inexplicably turned up–on my bookcase, no less! I guess the Elf was done reading it. Took him years, though.
All those little things of yours that go missing for no apparent reason… You might have Elves.
It’s better than having Gremlins.
Wasn’t there once a children’s novel, called “The Borrowers,” about little people who did this kind of thing? I seem to remember its being serialized when it was first published, and much later made into a movie.
Yes, there was a whole series of these books, plus the movie (which I do enjoy). If you remember that old comic strip, The Teeny Weenies, you’ll get the idea of The Borrowers.
We have families of elves n our house – we find things years later. We have become used to them.
