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 who I WAS when I got up this morning, but I think I must have been changed several times since then."
