Situation: I am doing my homework on the desk with a trash can standing by.
Alternative situations: I am studying at my desk with the fan behind me blowing a gentle breeze and all of the soda pop that I can drink at arm's reach located in the mini fridge near the door to my right. I am painting something on the desk before I leave to the bed at my left.
Question: Is the cushion on the floor or on the shelf?
