Situation: I am sitting on a chair in front of a table with several monitors on top of it, while there is only one chair on my left and a whiteboard behind me.
Alternative situations: I am sitting on a chair between two other chairs and watching the videoclip, being bothered by the light from a window on my left. I am sitting on the middle chair at the bottom of the room with my feet on the table in front of me.
Question: Can the number of whiteboards behind me be divided by three?
