Before they came here there used to be a sense of the other side of the world, a far-away-and-out-of-reach. Now they see how the continents run into each other like overgrown gardens – that Asia and Australasia are not separate at all but are made continuous by the islands that trail between; likewise Russia and Alaska are nose to nose, barely a spit of water to hold them apart. Europe runs into Asia with not a note of fanfare. Continents and countries come one after the other and the earth feels – not small, but almost endlessly connected, an epic poem of flowing verses.
