The "I have an idea, you can write it" tango

crowleycrow describes a situation familiar to any professional writer (or anyone who has spent any time actually listening to writers talk about the life of writing):

How often have we found ourselves in bars or parties listening to the conceptions (or worse the life stories) of people who have discovered we've written a book or books, or been trapped with someone who has generously offered to share with us a new, a strange, an absolutely unprecedented conception for a book, a story that ACTUALLY HAPPENED to our interlocutor or his cousin or lover.  We are invited to split the profits on the resulting work (60-40, 60 for him or her as having actually experienced or conceived the work.) "All you have to do," we are told, "is write it."
