Situation: I am sitting on middle cushion of the couch and facing the backpack.
Alternative situations: Relaxing on a couch with a pillow in my 8 o'clock direction, I can hear a cellphone ringing in a backpack in front of me. I sat down on the couch and looked at the whiteboard in front of me.
Question: What is on the ground that you carry on your back in front of me?
