Situation: There are some chairs in a row by the window. I am sitting on one of them but there is no more chair on my right.
Alternative situations: I just placed my backpack on the chair behind me now looking at the table in front of me. I am about to reverse and sit down on a chair with a backpack on a cushion in the bottom right corner of the room.
Question: How many chairs can I see directly in front of me?
