When I was a bit older, I designed and created a cross stitch sampler for my mother to hang over the guest room bed. It displayed the Orphan Annie quotation that Nana had taught me during the days of story-telling:
From ghoulies and ghosties
and long-leggitty beasties
and things that go BUMP in the night,
Good Lord deliver us!
That print hung on the wall of my bedroom for several years before I ever noticed the secret in the picture. It's a charm of sorts, I suppose, and maybe a promise of the surety of safety. Perhaps some might see more quickly but it took me a long time to look deep and realize the truth:
Should I give you a clue? Well, actually, I already have.
Spoiler ahead: I'm gonna tell the secret. If you want to figure it out yourself, avert your eyes.
(The monsters are all harmless. Now, say it with a Cockney accent: The monsters are all 'armless. Harmless. None of the monsters in the pictures have proper arms--thus, the monsters are armless, harmless.)
