The Caterpillar and Alice looked at each other for some time in silence: at last the Caterpillar took the hookah out of its mouth, and addressed her in a languid, sleepy voice.
"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 I was when I got up this morning, but I think I must have changed several times since then."
"What do you mean by that?" said the Caterpillar, sternly. "Explain yourself!"
"I ca'n't explain myself, I'm afraid, Sir," said Alice, "because I'm not myself, you see."
