Most of the authors I liked were dead, so it didn't seem like a safe occupation.
Gail Carson Levine
Why do you keep reading a book? Usually to find out what happens. Why do you give up and stop reading it? There may be lots of reasons. But often the answer is you don't care what happens. So what makes the difference between caring and not caring? The author's cruelty. And the reader's sympathy...it takes a mean author to write a good story.
Encourage children to write their own stories, and then don't rain on their parade. Don't say, 'That's not true.' Applaud flights of fantasy. Help with spelling and grammar, but stand up and cheer the use of imagination.
