Situation: I am pulling a chair from the stack of chairs in front of me and there is a window and a chair in my twelve o'clock direction.
Alternative situations: I climb over the chair in front of me and turn 180 degrees to face it, searching for fallen objects. I am facing the two blue chairs tying to get them out of the way so I can walk to the window pass the. Chairs.
Question: Is the amount of stack of chairs on my left odd or even?
