Situation: I am sitting on a chair facing the table with a window on my right and a chair on my left.
Alternative situations: I am reading an e-mail, while the chair on my left is empty and there is a nice breeze from a window on my right. I carefully selected which end of the table to teach from right next to the radiator and closest to the whiteboard so I could overlook my classroom.
Question: How many chairs are to the right?
