Situation: Standing in between a group of desks and a bookshelf while facing away from another bookshelf.
Alternative situations: I just got the books I needed from a bookshelf on my left and am about to walk past a sole black chair to leave the library. I am standing in the middle of aisle of bookshelf to my left and cubicles to my right contemplating about life.
Question: Can I be able to move backwards from my current position?
