The stories are not autobiographical, but they're personal in that way. I seem to know only the things that I've learned. Probably some things through observation, but what I feel I know surely is personal.
I want the reader to feel something is astonishing. Not the 'what happens,' but the way everything happens. These long short story fictions do this best, for me.
The deep, personal material of the latter half of your life is your children. You can write about your parents when they're gone, but your children are still going to be here, and you're going to want them to come and visit you in the nursing home.
People are curious. A few people are. They will be driven to find things out, even trivial things. They will put things together, knowing all along that they may be mistaken. You see them going around with notebooks, scraping the dirt off gravestones, reading microfilm, just in the hope of seeing this trickle in time, making a connection, rescuing one thing from the rubbish.
