I know when a story is finished when there is not a single thing more I can think to do to it. And since I know at the start what the last line will be, I know when I've reached that point as logically as I can that it's finished. As for the rewriting-it's not foolproof, of course, but if you're honest about having thought of every possibility and you still come back to what you have, what more can you do?
Amy HempelI think of the chimp, the one with the talking hands. In the course of the experiment, that chimp had a baby. Imagine how her trainers must have thrilled when the mother, without prompting, began to sign her newborn. Baby, drink milk. Baby, play ball. And when the baby died, the mother stood over the body, her wrinkled hands moving with animal grace, forming again and again the words: Baby, come hug, Baby come hug, fluent now in the language of grief.
Amy HempelI would like to go for a ride with you, have you take me to stand before a river in the dark where hundreds of lightning bugs blink this code in sequence: right here, nowhere else! Right now, never again!
Amy HempelI had a mother I could only seem to please with verbal accomplishments of some sort or another. She read constantly, so I read constantly. If I used words that might have seemed surprising at a young age, she would recognize that and it would please her.
