Where were these feet wanting to go?

Street photography can be so much fun.  One can click away and get lots of street photographs but I would much rather spend a few hours observing and capture just one unique moment, mood or expression.I spent a few hours in Boston's Quincy Market last weekend while my wife and her friend were shopping. Camera in hand I was people watching.  The light and shadows on the pavers was intriguing and I was hoping to capture something different. I noticed some confusion in the expression of this lady and that confusion seemed to be conveying a message that was reflected in her footsteps.
