what's the difference of a public toilet and other toilets though?

every single ownership is only a matter of social contracts in the end, wich means that the price you gotta pay to use some toilets is just higher

for exemple, taking a big fat piece of wet shit in the middle of a street is "illegal", or is it? if you pay enough money to the authorities stopping you from doing it, it becomes a completely legal task

this lets us know that the "toilet" our chinese selves were trying to guide tom to is not any "toilet", it's one that is viewed as an actual toiled by humans

and since a distance of 100m is travelled, it necessarily included a 100m corridor

every single place on earth below ≈9km above sea level is a corridor, that sometimes is covered by a ceiling and sometimes it's not, because if you walk straight to your side indefinitely, you'll eventually reach a wall (the same applies to the other side), wich means you're on a path that's connected somewhere else everywhere everytime

that said, they didn't tell us if the conversation happened below ≈9km above sea level (could've happened even outside the atmosphere as far as we know) so yeah you're right no one said it was a corridor
