I know writers keep their rejection letters cuz we're all self loathing like that. What was your nastiest rejection letter? Feel free to reword it to soften the blow (or not).
I've been fortunate in that I've only received the standard "Your work is not a right fit for this publication," which is basically a nice way of saying "Your work stinks." But at this point, a rejection letter for me is a pat on the back for even trying to send out manuscripts. In a year or so, when my apartment is wallpapered with them, they'll probably make me cry.
