I keep losing weight. There is not much left to lose. All my clothes are too big.
A few days ago I was walking Mabel and I saw the mother of one of my former prodigious students. She said "I didn't recognize you. You have lost a lot of weight. Are you ok?" She kept asking me, throughout the long conversation that followed, if I was ok. Her son was one of the most talented students I'd ever had. He is doing extremely well now, at Princeton.
I assured her that I was fine and that I had been swimming a lot.
But if I keep losing weight I might disappear.
