Or you became a Berliner.

(There's a small part of me that wishes I could've naturalized as a Berliner, not German — many (though obviously not all!) things I love about it are really about Berlin specifically, not Germany. Seeing "waiting at traffic lights to cross even when there's no cars around" being described as a German thing always makes me smile a bit; having worked for ~3y near Kotti. Nobody does that there.)
