Situation: I am looking at the trashcan and there are some backpacks on the floor on my left.
Alternative situations: Leaving the backpack on my left, I noticed an important note in a thrash can in my one o'clock direction, it might have fallen from a shelf in front of me. I throw away my wrapper into the trash can and a shelf is to my right.
Question: Are the shelves to my 1 o'clock full or empty?
