Scowling A.D. has very kindly read the first draft of my book for me, but he disagrees with a bit I've done about the differing personalities of Art Directors and Copywriters.

I wrote that Copywriters tend to be the talkers, and the strategists, whereas Art Directors prefer to say less and do more (even if what they call 'doing' I call sitting in a photographer's studio reading the newspaper).

Scowling A.D. complains that "Art Directors aren't always strong silent types - just as likely to be stereotypically louder, more energetic, more colourful, harder-partying, more passionate than Copywriters."

Who is right? If you meet a team in the pub, can you always tell which is which? Or is there no real difference between the two breeds?
