I got a nice rejection from a large agency today. Apparently I made it out of the slush pile.
Thank you very much for your query regarding TROUBLED WATERS. Although xxx read your letter with interest and saw merit in your premise, he is not enthusiastic enough to pursue representation and must, regretfully, pass. We wish you the best of luck elsewhere.
Still a form rejection, but one that says that some assistant liked it enough to pass it on.
I was doing a search on rejection letters and ran across this guy'stake on them. His "interpretation of what they're really saying" gave me a hearty laugh.
