Situation: I am solving some puzzles with a whiteboard and a backpack is behind me.
Alternative situations: I get closer to the whiteboard to understand better as I put my backpack behind me on top of a chair. I placed my backpack behind me on chair, writing on the whiteboard my topic of discussion for the meeting in front of me.
Question: What is closer to me between the whiteboard in front of me and the cabinet on my left?
