Situation: I am sitting on a chair by the short end of the table, facing away from some doors.
Alternative situations: I am sitting on the head of the table and eating my dinner and the picture frame is on my right side. I am having dinner on the head of the table sitting on the chair, my dinner plate on the table in front of me and I can hear children yelling and playing outside the window to my left.
Question: How many other chairs are sitting at the table?
