Situation: I am seated on a chair in the corner with another chair to my immedaite left and my right side against the wall.
Alternative situations: I am about to take the seat in front of me so that I can sit down on the table on my left side. I am sitting on a chair in the bottom right corner against the wall and I can see my backpack in cabinet in front of me by the door.
Question: I left my notebook near the door in what color backpack?
