Jack: [Reading to Aaron] "Alice took up the fan, and as the hall was very hot she kept fanning herself all the time she went on talking, dear, dear. How queer everything is today. And yesterday,things went on just as usual. I wonder if I've been changed in the night. Let me think. Was I the same when I got up this morning? But if I'm not the same, the next question is, 'who in the world am I?' Aha, that's the great puzzle."
