Who are you?

Colin Batty

'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?'
