" Home: it didn’t just seem as if home was a long way away,
it actually felt as if the whole concept of home was strange, a thing you used to believe in,
an ideology you’d once been passionate about but had now abandoned.
Home: the place where, when you have to go there, they have to take you in.
Somebody had said that. But once you had spent time on
the Wall, you stop believing in the idea that anybody, ever, has no choice but to take you in.
Nobody has to take you in. They can choose to, or not. (p. 54) "

― John Lanchester , The Wall
