One of the newest of my authors who are non-native English speakers, this one from China, wrote me to thank me for my editing. He addressed me as "Professor Katharine." :-) His thank-you is wonderful:
I am very impressed by your work and your precious effort and efficiency in editing this article. I have reviewed it and made revisions and answered the questions. Hopefully you can afford us further precious refinement of this paper.
Dear author, you have made my day.
