Up there down there is part of what could be seen productive subversive thinking. Outside the box. We know, like race, north being up is just a social construct and that flip maps are available.
It's fun to toss it out there occasionally. Like the US as just part of America being called America. Not fair. And man for humans instead of woan. Not just. That stuff.
When i taught i had a book called something like Teaching for Subversion. That's where i got the north is down idea. Kids loved it.
