I posted this in urbanism because I think it can be an offset for a nice discussion about living together in apartment blocks and the cramped conditions that arise, especially in sub-par block. Part of urbanism is urban living and discussions about how to tackle issues such as these.
Of course none of this would be an issue with good infrastructure, but that's something that can always be said. If everything was lollypops and gumdrops and so on.
I like the thread because both people start off reasonable and courteous and then end up calling each other names. I dislike it because, it being reddit, it just becomes a dogpile instead.
The hallway is already the bare minimum width for fire/medical emergencies without the bikes there. It's not reasonable in any way. It's also not the responsibility of the person being endangered to find a solution.
Edit:
Actually I'd go further. Safety codes are the bare minimum commons responsibility we have to each other. If someone values their convenience over your safety, they don't deserve your consideration, only your contempt.
