For a while, I was selecting articles about JD products. Many of them were written by a woman who included the following note with each article: "the [yes, lowercase] second reference is my husband who is a service manager at a John Deere dealership with 15 years of experience. He gave me the additional information not found in the manuals."
He did not, however, give her guidance on run-on sentences and the basic rules of punctuation and capitalization. I tried in several notes to her included with my rewrite requests. Fail.
To paraphrase the Soup Nazi, "no more John Deere for you!"
