We were hanging out together working on some things and he knows how I feel about putting em dashes in my copy.
So, after 30 minutes of back and forth- he says "okay all set is there anything else" and I replied: 'em dashes please"
And here is comes: " Great news! — the file already uses em dashes (—) consistently throughout. I don't see any stray hyphens being used as dashes"
