"Maybe that's what growing up means, in the end - you go far enough in the direction of - somewhere - and you realise that you've neutered the capacity of the term home to mean anything. [...] We don't get an endless number of orbits away from the place where meaning first arises, that treasure-house of first experiences. What we learn, instead, is that our adventures secure us in our isolation. Experience revokes our licence to return to simpler times. Sooner or later, there's no place remotely like home."
