You can see why it’s pointless to offer your ideas to a fiction writer. They’ve already got more ideas than they know what to do with or time to develop.
I dislike authors in any genre who set out to manipulate the readers’ emotions. If you’re going to get emotional reading a book, then it should come from the story and the characters themselves, not because the author manipulated the story so you would feel a certain emotion. And why, if you’re setting out to make a reader feel a certain emotion, would you want the emotion they feel to be sadness?
