I read this poem in the 5th or 6th grade or so, so that'd be 2012-2014 (somewhere in there). It was out of some packet copied out of a book for this language arts extension thing (I remember the book being very keen on something called "Jacob's ladders" I think, for difficulty of questions or something like it - this was part of a gifted/talented informal class). It was in english but it could very well have been translated. I remember very clearly that it started with lines like
Tell me a story, said Witch's child
Of the beast so fierce and wild
And ended with a line like
Something nice to make me sleepy.
I also remember it was reasonably long - it filled up the whole page, which was around 11x13 since it had been copied, in a normal size font with a small illustration at the bottom, I think.
I have no idea how I've remembered it this whole time, so I thought I might actually try to find the poem. Thanks!
