attic stairs - underneath

Why include a shot of the underside of the attic stairs? Simply for the sake of explaining that the back of the closet in J & J's room was opened up, so that one could crawl to the back and look up to see what you see here. Why this was accessible I have no idea, though I imagine that you could perhaps hide someone in the space if you absolutely had to. Or stash valuables in such a nook. I don't recall ever finding one of those hideaway spots in any of the floors (and yes, houses of that era had such places; I specifically recall a bunch of us neighborhood kids running around through an old house waiting to be torn down and being exultant at finding just such a feature, though sadly there was no treasure there).
