Situation: I am sitting in an office chair and there is a table surrounded by some chairs in front of me and two office chairs to my left.
Alternative situations: I am sitting in a chair on one end of a table with a stand behind me at 6 o'clock. I am sitting on a square blue chair at the head of table reading a book on the desk in front of me and I can see my boss from from me on the other chair.
Question: How many chairs are behind me?
