Situation: I am sitting on the chair reaching out for the window.
Alternative situations: I am looking at what is happening outside through the window in front, there is a bookshelf on my right side. I am sitting on a chair on the right side of the room with my arms resting on the desk as I look straight out the window but blinded by the bright sunlight outside.
Question: How many file cabinets are there under the desk on my left?
