I love editors. The reason I love editors is they save me from embarrassment. I make errors and typos with punctuation and seem to miss them when I self-edit. This is especially true for commas. I just can’t seem to get them right. I think I have them figured out, but when I get my edited manuscript back, I learn that some savant surreptitiously changed the rules ... again. Or at least I prefer to think the rules changed, rather than I remain befuddled.
Many people think punctuation is boring … but not The Oatmeal. They even sell posters suitable for framing about different aspects of grammar. Maybe you can even get your teenager to replace their Janelle Monáe poster with one about how to properly use an apostrophe. Good luck with that.
