Situation: I am typing on the keyboard with a chair on my left.
Alternative situations: I am standing on the backside of chair, facing the desk, using my left hand to touch the bag on the desk on right of me where I am standing. I am standing behind a chair with chair facing to the left side of the room while I am typing on the keyboard on the desk in front of me.
Question: Is the amount of computer towers in the room odd or even?
