Some submissions seem to demand an response, but there isn't anything to say. Like the middle-aged woman on disability who can't work and sees the publication of her poetry book as her only hope for a decent life. At times like that I want to get the hell out of this business. Seal the mailbox to keep the needy inside. It's like a confessional.
Perfect strangers come with their deepest fears and hurts, and the thinnest strand of hope.
There's nothing here to tie it to. Then there are some submissions that really ask for it, but the adult thing to do is ignore them. Put your name and address on the first page of each work. Name, page number and number of pages on all additional sheets. Plain copier paper is perfect.
