Lewis Carroll

“It’s no use going back to yesterday, because I was a different person then.”

“'But I don't want to go among mad people,' said Alice. 'Oh, you can't help that,' said the cat. 'We're all mad here.'”

“'When I use a word,' Humpty Dumpty said in rather a scornful tone, 'it means just what I choose it to mean - neither more nor less.'”

“Who in the world am I? Ah, that's the great puzzle.”
