Wonder

"Dear, dear! How queer everything is to-day! 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? I almost think I can remember feeling a little different. But if I'm not the same, the next question is, Who in the world am I? Ah, THAT'S the great puzzle!"
