I still don’t know the difference between “upstream” and “downstream!”
Envoy uses the opposite definitions from what I’m used to. And has a perfectly cromulent explanation for why; I’m convinced. But now I don’t know why I started calling them the opposite.
From your example, one could envision an extended edition where, shortly after the shoe goes out of view[1] floating past him, someone shouts "anyone missing a shoe?"
That response would then come from downstream from Darkly.
My point was that it's a matter of perspective. And it requires a certain well-defined gradient (the river), I don't think "upstream" and "downstream" make much sense when all you have is a lake.
