Caterpillar: Who... are... you?
Alice: I- I hardly know, sir. I've changed so many times since this morning, you see...
Caterpillar: No, I do not 'C.' Explain yourself.
Alice: I'm afraid I can't explain myself sir, because I'm not myself, you know.
Caterpillar: I do not know.
Alice: Well, I can't put it any more clearly, sir, for it isn't clear to me.
Caterpillar: You? Who ARE you?
