Where is it? That line that marks the end of "no news is good news" and the beginning of "no news means no thanks"?
Don't get me wrong -- I know I'm not there yet. My manuscript has only been gone a couple of months; a blink of an eye in the publishing time-space continuum. But I can't help but wonder that as more time passes without a word, my chances of getting a "yes" from the publisher and agent lessen dramatically.
Does it ever happen? Have you ever heard of a publisher buying a manuscript after having it for months with no communication with the writer?
