Moore writes with humour and with intelligence. Here's the first paragraph from the introduction:
"Perhaps you are standing in the bookstore, scanning this introductory chapter, wondering just what sort of book you have in hand. You are a good-looking person whose minor flaws seem to only accentuate your considerable charm. You are intelligent. And immune to flattery."
So yes, Moore writes with humour and with intelligence. But we all make mistakes and I thought Moore made one on Page 18 in a four-page essay dedicated to teaching readers how to use an "em dash". So I wrote an e-mail to him on Sunday night.
Subject: A question regarding the em dash as used in your book, "Dear Mister Essay Writer Guy"
