Situation: I am doing my homework on a desk. There is a bookshelf directly to my right and some other desks to my left.
Alternative situations: I pulled up a chair at the desk and there were two desks to my left. I am sitting on a chair and desk on the right ide of room cubicle taking a nap while my head is on the desk.
Question: How can I move the chair get out of this desk if I push myself back?
