After all, who does? Aside from those whackjobs you see from time to time and who, to be honest, I see at the university more than I used to. But that wasn’t Sara’s style. And the university had nothing to do with it. She took the first step, the real step, after some false starts, in selling cars. Subarus. She said it seemed like a good idea at the time to sell cars, and I guess it was. But she went over the cliff not simply because of greed. What’s greed? Just money. She had an idea, she said, to track me down, wherever I was (it might take some doing, but Sara was never afraid of things like that) and she’d be dressed in that stuff you see in Vogue and other magazines, Gucci, Versace, Chanel, and she would have, behind her ears and on her wrists, perfume that would make me think paradise had just walked up to my apartment. Wouldn’t that just blast all that interstellar medium, all those equations, all my cosmological theories into dust? “But you were too smart to think that was going to really happen,”
