“You can’t argue with them, because they live by an entirely different logic. You come to a town where everyone’s dressed all in white, for example. I’m thinking of a town we visited once just outside our usual territory, north of Kincardine, and then they tell you that they were saved from the Georgia Flu and survived the collapse because they’re superior people and free from sin, and what can you say to that? It isn’t logical. You can’t argue with it. You just remember your own lost family and either want to cry or harbour murderous thoughts.”
