Situation: I am sitting on a chair under the window behind me, while there are more chairs on my left and no chairs on my right.
Alternative situations: I am sitting in front of the window on the chair furthest from the television looking at the whiteboard on my right and the one in front of me taking notes. I placed my backpack on top of the chair behind me and to my left was another chair.
Question: Is the amount of window behind me odd or even?
