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."
"What do you mean by that?" said the Caterpillar sternly. "Explain yourself!"
"I can't explain myself, I'm afraid, sir," said Alice, "because I'm not myself, you see."
"I don't see," said the Caterpillar.
"I'm afraid I can't put it more clearly," Alice replied very politely, "for I can't understand it myself to begin with; and being so many different sizes in a day is very confusing."
"It isn't," said the Caterpillar.
"Well, perhaps you haven't found it so yet," said Alice; "but when you have to turn into a chrysalis-you will someday, you know-and then after that into a butterfly, I should think you'll feel it a little queer, won't you?"
"Not a bit," said the Caterpillar.
"Well, perhaps your feelings may be different," said Alice; "all I know is, it would feel very queer to me."
"You!" said the Caterpillar contemptuously. "Who are you?"
