Situation: Standing in between two tables while facing the blackboard closest to the door.
Alternative situations: I stood up to go draw on the blackboard which is directly in front of me with two chairs below it. There is a table on either side of me. I walk back to the opposite side of the room and stand between the two tables I started at, this time I turn to face the blackboard.
Question: How many chairs behind me are facing the same blackboard as me?
