Situation: I am looking at the window waiting for my uber drive to arrive with my lunch so I can go out through the door on my left within reach to get it and eat it on the table behind me.
Alternative situations: I am looking out the window on the left side of the room watching for passerby'ss outside. I am string at the street outside and there is one office chair behind me and another one on my left.
Question: What is the major component of the window in front of me?
