The first few moments in a new country are always dizzying; surreal, even. It feels like walking on to a movie set. You somehow expect to run into an edge of this new world. It's the opposite of the sailboat scene in The Truman Show, when he finally figures out his whole life is an artificial construct and ends up putting a hole in the in the set with his sailboat.

Gradually you come to terms with the idea that the new place is real, that this set is where millions of lives play out every day. We are broader, better people for this realisation. As we move around in the new space, we come to understand that other people's environment and circumstances can be radically different from our own. I believe this is a profound idea.
