Situation: I am facing a door, while having a trash can on the left and another one on the right.
Alternative situations: I just discarded my phone on the trash on my left by accident, so I left the room via door in front of me to grab the janitor to help me get it. Using my left hand, throwing out my apple seeds and right hand to open the door handle in front of me.
Question: Is there an odd or even number of office chairs in a room?
