Situation: I am crouching changing the trash from the trash can and on my left side is the door.
Alternative situations: I am walking out the blue door in front of me after sitting on the chair behind me during a meeting. Throwing some wipees into a trash can in front of me, I am listening to the dialog behind the door in my ten o'clock direction, while there is no one at the table in my 8 o'clock direction yet.
Question: What is the shape of the table behind?
