Situation: I am sitting on one side of the desk with my feet on the floor while facing a shelf and there is a window on my right within reach.
Alternative situations: I am sitting on desk, window to my right and looking at the computer tower in front of me wondering if it on. I am sitting on the edge of desk in the top right corner of the room whistling a song and the sun is shining on my face from my right side from the window.
Question: What is behind the computer tower that is in front of me?
