Situation: I am facing a trash can, while there is a door behind me, a paper bag on my right and a shelf on my left.
Alternative situations: Walking out of the door and down the hallway with the kitchen counter to the right. Leaning to the door behind me I remember that there are more things that need to be cleaned up after I saw the trash can in front of me.
Question: How many open doorways are on my left side?
