Situation: I am sitting on a chair facing the table and the window farther from the whiteboard with no chair in the same row on my left.
Alternative situations: Sitting in a chair with my elbows propped up at the corner of a table, I can see out of the window almost directly ahead of me across the room. I am sitting in the chair at the board table, brainstorming about topics.
Question: How many chairs are to my left?
