" All his life he'd dealt in honour and service, the way a furrier deals in furs or a vintner in wine. On his lips the terms had had specialised political meanings, and he'd long since stopped thinking about what the words stood for in the world at large. Now, unfortunately a little bit too late, he'd been granted a little gleam of insight; service is what makes you stand in the line when nobody would try and stop you if you ran away, and honour is what's left when every other conceivable reason for staying there has long since evaporated. "
