upside down world

Sub
What if we could have a world upside down in sight but also a world where things went the wrong way around but we could never get used to it as if we were planted on the planet from somewhere else and we knew this but we could never get used it. What would that be like ? I think about this and what if we were to leave school and then get a full time job and then 20 years later that was the time you got to go to university and have all the fun and do silly things why can’t that be the norm or upside down ?
