who are you?

«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.'

'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 some day, 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?'

Which brought them back again to the beginning of the conversation. Alice felt a little irritated at the Caterpillar's making such very short remarks, and she drew herself up and said, very gravely, 'I think, you ought to tell me who you are, first.' »

and you... what would you do if you found a caterpillar with such pertinent question?
