"It's no use going back to yesterday, because I was a different person then." "I don't think -- " "Then you shouldn't talk." "Who in the world am I?' Ah, that's the great puzzle!" Three great quotes from one of the greatest classics, Alice's Adventures in Wonderland, a 1865 English children's novel by Lewis Carroll. A young girl named Alice falls through a rabbit hole into a fantasy world of anthropomorphic creatures. It is seen as a prime example of the literary nonsense genre.
