Middle school is the weirdest thing. I can't see how the teachers get anything done with so many students running around everywhere. How do they grade work with anywhere between 90-180 students turning in homework at the same time? Robin Dunbar says that the human brain can only handle around 150 meaningful relationships at a time, so how do they do it? Even though there seem to be so many more people, the entire school is so much smaller than an elementary school.
