Picture a scene. A setting sun. Someone, perhaps a dark-haired stranger, is in front of it. How about a building covered in snow? Or a stuffed elephant. On a table? A tree is on a table. A book is on a table. And a flat-screen TV isn’t. A zoo, somewhere. Zebras march. Seagulls roam. Black bear, a former captive, is on a bridge. Is she eyeing the sheep – those in front of a random building? Taking it all in, as confidence surges, a young man takes a selfie.
