I don't have him anywhere, face down or face up or any other position! And he said, "significantly shorter," and called me "perfectly reasonably sized" which is no where near "significantly shorter" than he is. Clearly it is not I who may or may not be the cause of your friend's position on the sofa.
Also, if by some chance I had him "facedown on the sofa," I'd be giving him attention in person instead of writing to him on a journal. I have at least some manners about these things.
