Situation: I am studying on a desk while there is a trash can behind me. To my left there is another desk.
Alternative situations: I am doing my homework on desk cubicle on top left corner of the room and by backside is turn to the tables behind me. I am sitting on a chair and cubicle desk in top left corner with my head down on the desk sleeping.
Question: What is nearer to me, the trash can or the backpack?
