Situation: I am sitting on the middle cushion on a couch facing the piano across the room. There is no more couch behind me.
Alternative situations: I am sitting on the middle of the sofa furthest from the brand-new piano I just bought admiring it. Picking up a magazine off the large square coffee table, with two recliners on either side.
Question: Is the shape of coffee table in front of me round, square or rectangular?
