Situation: I am on a chair, and there is a TV behind me.
Alternative situations: I sat down at the head of the table and to my right was a whiteboard. I sat at the table and there was a chair to my left and right. I looked at the whiteboard to my left while I sat in the chair at the table. I sat at the end of the table and to my right was the whiteboard. I ate lunch at the table and to my right was a whiteboard. I placed my laptop right down on top of the table and to my left was a chair.
Question: Which one is furthest away from me, a backpack or a chair?
