Situation: I am sitting and working on my keyboard by the window. There is a whiteboard directly behind me. No more table is behind me.
Alternative situations: I moved to this spot of the office to keep me warm with the radiator on my right while I use the two monitors in front of me. I am sitting down while writing a work report on my monitor with the sun shining through on my right.
Question: Is the amount of radiator on my right odd or even?
