it's best to keep this one a light and easy series of jokes about punctuation and not get into what's "easy" in a workflow because ultimately we're going to go to a pretty dark place about the gender and age breakdown of, say, copy editors versus people submitting double spaces after periods.
I did point out the person about to die rather than give up double spaces after a period used only a single space.
the end
Why not just do a global search and replace and move on?
Yeah that’s something people should do before submitting to an editor or whoever is charged with fixing the document
Sometimes you can! But in my experience, people who refuse to unlearn double spaces may also refuse to learn to use good templates with tabstops, so a global change can cause bigger issues.
good advice indeed
