Yes, the Monkeysphere. That's the group of people who each of us, using our monkeyish brains, are able to conceptualize as people. If the monkey scientists are monkey right, it's physically impossible for this to be a number larger than 150. Most of us do not have room in our Monkeysphere for our friendly neighborhood Sanitation Worker. So, we don't think of him as a person. We think of him The Thing That Makes The Trash Go Away.
