Situation: I am standing near the curtain facing the black coach and there is a bunker-bed on my left.
Alternative situations: I am glancing at the bunk ahead of me before I am going to use the ladder on my left to get up on the top bunk. I want to climb to the bunk bed on my left side and take a nap after having a long day.
Question: What is on the 12 o'clock of the shelf that is on my right?
