Looking At You, Looking Away

You have the stage: the brick wall of a house lit by glorious evening sun, plus a curious window. All you need is for some passer by to animate it with a shadow. But the photographer's line of sight sets up a force field, a zone few are willing to push through. This lady did walk past, when I waved her on, but her halted, hesitant stance proved more interesting, and her head's shadow (expressing her desire to turn away) is perfect.
