One of my favourite article from The Economist. I first read it in an airport near Nyköping, Sweden. Snow was falling slowly against the dark sky. It was deep in December. And I was waiting idly for a flight to Berlin the next morning.

'with the passage of time, something does happen to long-term foreigners which makes them more like real exiles ... The [homeland's] culture, the politics and their old friends all change, die, forget them. They come to feel that they are foreigners even when visiting “home”. '
