The first thing we did when we met was exchange manuscripts. (Actually the second thing. The first thing was his correctly using a semi-colon and my being impressed by it.) He is a better writer than I am and will some day achieve huge success, and meanwhile he is a very useful person to have around when I've just written two new chapters that stink and Need Everything Fixed And A Pep Talk Too. He comes up with exactly the right word (slammed not pounded, that's perfect) and exactly the right twist to a mundane sentence.
In return, I edit his work by inserting too many em-dashes--because even though his semi-colon use impresses me, no one else needs to see those nasty things all over the place.
So now I have my 11,000 words back with Track Changes all over them and tomorrow there'll be no time for time for Real Estate Intervention or Curb Appeal because I have 11,000 words to polish.
It's awesomely brilliant to be married to another writer.
