Situation: I am sitting on a chair working at the desk with the window farther from the door to my right.
Alternative situations: Taking some notes from a video on my monitor before I file them up on the cabinet that is on my 8 o'clock. I am standing on my desk. Chair behind me to get a better top view of the couch in front of me on the left side.
Question: What is upright and flat on my desk in front of me?
