Situation: I am standing in between two groups of tables, facing a table, while having another table with a backpack on top of it behind me.
Alternative situations: Just left my backpack on a table behind me and reached for a chair in my two o'clock direction. I had placed my backpack down on the table behind me and there was another table in front of me.
Question: Which one is closer to me, the backpack or the trashcan?
