The city does not care if you've wanted to settle there. Even if you're suspicious about it, and try to avoid interaction, it surrounds you with it's network of shady streets and tram tracks. Months are passing, and then suddenly one realises that he knows most of these streets, tracks, underground tunnels and skyscrapers.

Because the city wants you to assimilate with it. And your word does not really matters.

And so I've become a citizen.
