What was that again?

"I quite agree with you," said the Duchess; "and the moral of that is--'Be what you would seem to be';--or, if you'd like it put more simply--'Never imagine yourself not to be otherwise than what it might appear to others that what you were or might have been was not otherwise than what you had been would have appeared to them to be otherwise.'"

"I think I should understand that better," Alice said very politely, "if I had it written down: but I can't quite follow it as you say it."

"That's nothing to what I could say if I chose," the Duchess replied, in a pleased tone.

"Pray don't trouble yourself to say it any longer than that," said Alice.

"Oh, don't talk about trouble!" said the Duchess. "I make you a present of everything I've said as yet."
