 And that's maybe the sort of poster child example of hostile design, hostile architecture, right? This is we want to control a certain behavior. We don't want someone sitting here, so we'll put some spikes there. And, you know, that's a weird one because when you see it, you know just what it's for. But one of the things that's really interesting about hostile design is that so many of the other examples are not nearly as obvious, even if they're doing the same thing.
