Situation: I am sitting on an office chair facing another one and there is a couch behind me.
Alternative situations: I am at the computer workspace with two monitors and I turned to the left to ask my co-worker a question. I am sitting on the chair facing the plant on the side of the room with one hand on my lap and the other on the desk to my right.
Question: What can I see on the top of a bookshelf directly in front of me?
