Situation: I am sitting on an office chair typing on the whiteboard behind me.
Alternative situations: I walk across the room and sit on the opposite chair, now facing the other computer monitor 180 degrees from the other one. I am sitting in chair and desk whirl my head forward staring closely into the double monitor in front of me, window is on my right.
Question: What is beside the backpack that is on my 10 o'clock?
