Situation: I am sitting on an office chair that is not at the table with the chair on my left within reach and I am facing the table.
Alternative situations: I am sitting on the chair bottom right by the wall, wondering when this meeting will begin, a table is seen in front of me. Sitting between two office chairs, relaxing in my free time , realizing how many chairs there are in the room.
Question: What is is substituted for a wall on my left?
