Situation: I am standing and the red backpack is on my right side and I am facing wall across the room.
Alternative situations: I am searching for something to write on the backpack on my right so I can start writing what's on the whiteboard on my left. I just put down my backpack on the chair to my right side, walked towards the cabinet in my top right corner to get a pen and paper to write on.
Question: Is the whiteboard to my left or right?
