This plastic bag stuck in a tree outside my window...

This plastic bag stuck in the tree outside my window at work stares at me all day long. At the moment, it is an albino snake, coiled around the outer branches of a barren sidewalk elm. When the wind picks up, it's head bobs up and down and a long tongue protrudes from its mouth and smells the air. People passing by show little concern for the danger lurking from above.
