Situation: I am sitting on the edge of the bed facing the desk with the nightstand within reach.
Alternative situations: I got up out of my bed and grabbed my phone from the nightstand to my left. Sitting on the edge of the bed, with a nightstand in my 10 o'clock direction, I can hear someone knocking on the door in my 4 o'clock direction.
Question: How do I have to turn to see the radiator?
