If the Muse is unwilling to co-operate, it's no use forcing it. Maybe, as someone else suggested, some other piece of her art might do it for him. I know that sometimes SeverusMuse will put the entire story in my head at once, and it will just flow from my fingers. Other times, it takes me forever to write a single paragraph of text. I've learned to just do stuff that interests HIM, because it's just easier that way. If he doesn't want to get involved with something, he'll just say, "Well, good luck with all that", pour himself a scotch, pick up a magazine, and leave me to go it alone. And THAT'S certainly no fun for me.
