““It's probably the closest thing resembling research I ever do (except for this last book, which took more traditional research) - listen to speech patterns. They're everywhere, on the train, in the street, in the shops, on TV, wherever you are. And yes, everyone's speech pattern changes depending on where and to whom they're talking. Ears open. Literally. (which is the word said about sixty times in five minutes by a group of teenagers sitting further up the train from me on my way here).””
