Beautiful song.

I know that the museum island (and the Brandenburg Gate, and Potsdamer Place etc) are in Berlin. But what's the context of this? Is she referencing something in particular?

Stuff like "you'd taken your last ever bus" and "waving is all that you do" makes me think of someone who's become rich, perhaps even become royalty.

Mostly it seems like a song about friends who've gone in different directions. It's gorgeous, anyway.
