Blake concludes by saying "Now, this isn’t a complaint article about editing clients. Rather, it’s meant as a curtain-parting glimpse into what editors deal with in terms of unprepared, underprepared, or naive clients. It’s what not to do when working with an editor."
He goes on to say, "Additionally, many of these 'monsters' come by it honestly. Because they don’t live, breathe and eat writing and publishing as editors do, they just don’t know what’s conventional or expected. Most editors understand this and are glad to help new authors learn the ropes—so long as the author is receptive to expert advice."
Of course, most clients are not like those described. Most are reasonable people looking for expert advice on their manuscript and open to input to ensure their manuscript is as good as it can be. They are happy to learn about the process and to identify the strengths and weaknesses of their writing so they can eliminate any bad habits for next time, and pleasantly surprised how good their writing is after an editor as been over it. The editor-client relationship is almost always positive, Blake's occasional monster notwithstanding.
