"Who are YOU?" said the Caterpillar.
This was not an encouraging opening for a conversation. Alice
replied, rather shyly, "I--I hardly know, sir, just at present-- at
least I know who I WAS when I got up this morning, but I think I must
have been changed several times since then."

"Tut, tut, child!" said the Duchess. "Everything's got a moral, if only you can find it."
"But I don't want to go among mad people," Alice remarked.
"Oh, you can't help that," said the Cat: "we're all mad here. I'm mad. You're mad."
"How do you know I'm mad?" said Alice.
"You must be," said the Cat, "or you wouldn't have come here."
Alice laughed. "There's no use trying," she said: "one can't believe impossible things."
"I daresay you haven't had much practice," said the Queen. "When
I was your age, I always did it for half-an-hour a day. Why, sometimes
I've believed as many as six impossible things before breakfast."
