Situation: I am facing a desk and a monitor while there is an end table to my left and a chair to my right.
Alternative situations: I' m standing in front of the desk left of the office chair and staring out the window in front of me , thinking about lunch. I am standing by desk with a monitor on my right and looking through the window watching for the pizza guy to arrive at my door.
Question: What is in the middle of the wall I am facing?
