Situation: After dropping my bag on the chair behind me, I walk towards the window to let some fresh air in.
Alternative situations: I just finished putting my backpack on the chair behind me and am about to go sift through some shelfs under a big window in front of me. I am looking at the books in the shelf to the right of the round table where my backpack is.
Question: What could I see on my right, in a corner, on the top of a bookshelf?
