Situation: I am getting a couple of bags, while there is a drawer with a shelf on top of it on my right.
Alternative situations: I lost my keys so I am looking for them inside the bag that is in front of me, before I was searching in the bag that is on my left too. I am grabbing by bag hung on the wall in the top left corner of the room.
Question: Is the amount of shelves in the room odd or even?
