And I would say again that honesty is critically important, but so is care. I don't steal other people's lives, but certainly believe every writer is informed by his or her own experiences, as well as the experiences of others.

And ultimately it belongs to them. I do not. I am afraid of my computer the way it is. I do have an address where people can write to me though. Lake St. 160, Oak Park, Illinois, 60301.
