You know how you read a book all over again, you'll probably know the story. Or if you watch a movie again, you'll know how it begins and how it ends. Maybe when you listen to your song repeatedly, you'll know the lyrics. Life isn't anything like that. We may know the story but it does change. The story carries on, it does not end. Scene changes every single time. When we make mistakes, we may make the same ones all over and over again but with different people or in different situations.
