A Walk After Dark

Imagine this: It is dark outside, stormy and moonless. A woman enthusiastically calls her dog: “are we going on a walksie?” The dog wags its tail and joins its owner, and together they step outside into the rain. The designated place for dogs to do their business is in a deserted part of town. There is no one around, the sidewalk is empty. Until they come across a white, unmarked van standing stationary next to the sidewalk. All of a sudden the woman is not carelessly walking her dog anymore. Her heart starts beating faster, and she slows her step. She stands still. Then she quickly crosses the street, only to avoid walking next to that parked van. Just to be sure; you never know.
