Situation: I am sitting by the desk cleaning the keyboard in front of me. There is another chair to my right.
Alternative situations: I work on the keyboard at the desk and view now and then at the monitor. I sit in the chair writing in my record book and there is a shelf on my left. I did my homework at my desk and to my right was my monitor. I grabbed the chair in front of the desk and to my right was a door.
Question: What is behind me?
