Situation: I am pulling a chair from a stack of chairs and there is no stack of chairs on my left and there is a window in my three o'clock direction.
Alternative situations: I am about to finish wiping off dust from the stack chairs on the right side of the trash cans. I want to sit on the stack of chairs just in front of me, there is a door just behind me.
Question: How many trash cans are to my left?
