Just now: a rejection for "Manassas Magic", from IGMS -- form rejection. Form rejections are particularly hard on the soul, I think. (Although... I suppose they are better than "What on earth are you thinking? Writing involves TALENT, you idiot! Go get a real job!" Which is what I'm usually assuming the editors are writing in response to my work. Optimism is the writer's best friend.)

So breathe and send it out again.
