Situation: I am sitting on a chair, while having a desk at my left and there is a bookshelf behind me too.
Alternative situations: I am standing up in front of the light grey colored office chair as I stair aimlessly at the window ahead of me. I am standing in front of the light colored grey chair and trying to get a glimpse of outside window from where I am standing.
Question: Which direction should I go in order to grab my backpack?
