Situation: I am facing the door and there is a chair on my immediate right within reach.
Alternative situations: The door in front of me was stuck behind the desk so I was moving the desk on my right a little bit. I am standing on the left side of the chair with a blue back pack and facing forward with the window on my left, the sun is shining on my left cheek of my face.
Question: What part of the window on my left would shatter if someone threw a rock from the outside?
