" You ask if I miss having my vision. And I give you polite answers and deflections so you won't worry about me. But I'm not afraid of blindness. I made sure when I was young to see everything. The ocean, the sky, every kind of person on Earth, all the animals that were left before they were gone. I even saw space from inside, the Earth as it trailed away behind us - even if only in my mind. I've seen sunrise on Mars and my own baby, though she's nearly grown up now and doesn't talk to me much.
"I'm about as afraid to die as I am of being blind. What else is there to do or see? I've seen it all, and all that's left is reminders that it's gone, all of it gone. "
