Situation: I am about to push open the door in front of me violently because I am upset with my coworker.
Alternative situations: I have my left hand holding the door handle on left side of the door to pull towards me as I exit the room going backwards. I push the door to go out and there is a window behind me to the right.
Question: I going to throw away my gum, how many y chairs do I need to walk behind?
