Situation: I am picking up my bag on the floor.
Alternative situations: I walk over to grab my bag and in front of me is a whiteboard and to my right is a chair. After wiping the whiteboard in front of me and tossing dirty paper into trash can in my 10 o'clock direction, I am looking for a water bottle in my bag.
Question: What is coming through the window that is providing light to the room on my right side?
