Okay, I have to ask.
Kinda spoilers ahead...
Was the story about the old horse and the unicorn a myth that already existed that you borrowed or did you write it yourself? That was genuinely one of the sweetest fables I've heard in a while. It's so simple and short, but it's so careful to pull at your heartstrings in the rawest way. All to have a happy ending about living for eternity that doesn't even bring up the thought that immortality could become torture.
I think it's the most wholesome story I've ever heard that involves a wish-granting genie-type character. It definitely elicited the strongest reaction I've had to a fable. And again, all that in such a short little story!
