In conversation, midi also means noon (e.g. used as "meet me at noon"), which for my brain correlates more with central than south, given the context of a day.
Not a linguist, so what do I know, maybe someone else can chime in.
So we winged it and got off at Zuid (since Noord felt wrong and Centraal definitely seemed wrong) and luckily it was the right one.
We did have a wonderful evening (perhaps too much so) the night before at a nice craft beer bar in Leuven which had 100 beers on tap, and it had just bought over by a nice young couple as well. So perhaps neither of us were in the right state that morning to navigate a confusing train map! Good memories.
I feel like running it locally it just asking for trouble, YOLO mode is the way to make this whole thing incredibly efficient, but trying to somehow sandbox this locally isn't the best idea overall.
