Situation: I am walking away from the couch in the middle of the hallway between some chairs and a bookshelf.
Alternative situations: I am standing in the middle of room in between bookshelf on my right and staring at the door wondering why it not shut closed in front of me. I am looking forward in the middle of a room with the entire bookshelf to my right and a row of monitors to my left.
Question: Is the amount of monitors on top of the desk at my left odd or even?
