Situation: Standing in front of the carbinet, I am about to walk into a corridor with many chairs on both sides of me .
Alternative situations: My back is facing the brown cabinet but all I want to do is take out trash cans out of the room because it stinks, the trash cans are behind me to the right. I just placed my cup on top of cabinet behind me and walked to the other side of the room.
Question: How many types of chairs are there?
