Situation: There is nothing behind me, and I am sitting on a chair at the short end of the table.
Alternative situations: I sat down on the chair that is on the end of the large table but before I left my empty cup of coffee on top of the coffee table at my right. I am sitting on the chair at the bottom portion of the table tapping on the table with my knuckles in front of me.
Question: Which direction is the whiteboard to me?
