Situation: I am resting on the middle of a three seater bench and there is a two seater couch on my right.
Alternative situations: I am having a cup of coffee while sitting on the bench, there is a coffee table behind and in front of the bench. I am sitting down on the bench to take some coffee and there is a coffee table in front of me and another coffee table behind me.
Question: Is there an odd or even number of couches in the room?
