from The Elephant Vanishes, 1993.
"This is my seventeenth straight day without sleep."
I liked this one a lot. Wouldn't your life be very different if you no longer required sleep? This woman has the sleepless condition and uses it for a task I would, to wit, reading more. She reads Anna Karenina mostly, and muses on her life. Does it have to end the way it does? Probably. Fabulous story.
