Situation: I am opening a bathroom stall door and facing it while the mirror is in my seven o'clock direction.
Alternative situations: I am looking at the bathroom stall door in front of me, and there is another bathroom stall on my right. I am walking through a bathroom stall door with another bathroom stall door to my right and a sink behind me at 6 o'clock.
Question: What shapes are the four sinks behind me?
