“All through my life I've had this strange unaccountable feeling that something was going on in the world, something big, even sinister, and no one would tell me what it was."

"Everyone?" said Arthur.
"Well, if everyone has that perhaps it means something!

"Maybe. Who cares?" said Slartibartfast before Arthur got too excited. "Perhaps I'm old and tired," he continued, "but I always think that the chances of finding what out really is going on are so absurdly remote that the only thing to do is to say hang the sense of it and just keep yourself occupied.”
