Situation: I am facing the table and there is an armchair on the left and right of that table.
Alternative situations: I grabbed my book off the table before I relaxed on armchair on my right side. I am facing the table and deciding which chair to sit on my left or right side of me. I grabbed a tissue from the tissue box and there were armchairs to the left and right of me. I placed my drink down on the table and there was an armchair to my right.
Question: Is there an even or odd number of windows to my 3 o'clock?
