I'm writing a book for a publisher and it promises to be a character-building exercise.
They want chapter introductions that pat the user on the hand and tell them, today class first we're going to X and then we're going to Y and then after that Z but first I'm going to tell you that we're going to do X Y and then Z because before XYZ you need to know that X, Y, Z.
Are you really ready for X? Okay good, because we're going to discuss X before Y. I told you that is all leading up to Z right?
