A funny thing happened when I got feedback from the “kick-start editor” for my debut novel, Wish I Was Here. She checks the first 20 pages of your manuscript to give you an idea of stuff to look out for in the rest of your book. Mainly, it was all about the commas.
This cracked me up because commas were Mark’s primary concern when he did a run-through also. I specifically remember him adding a comma before “then” somewhere.
This lady? “No commas before then unless what follows is a complete thought.”
I understand the mechanics of that, sure, but what about when there’s a natural pause where the comma would go?

I’d love your guys’ take on The Great Comma Debate. Here are two examples. Please vote 1 a or b and 2 a or b.
