Situation: I am facing a backpack that is on top of a chair, while having a whiteboard on the left and another chair behind me.
Alternative situations: I just got up from the chair right in front of the cabinet behind me and getting my bookbag from the table in front of me before heading home. I looked through my backpack in front of me and to my right was the table and chair.
Question: How many sides does the table behind me have?
