Dr. Laura: So you might want to-don't argue with the kid, you just say, "When you can take care of yourself, you make your own rules. Until then, I am your rules. Now, if you get a job, on the average, what do you think you'll make?" Get out the Monopoly money and play it with her. Say, "Right now, you're living free. Don't you think you owe something back for living free?"
Carol: And what is so difficult about that? I don't think I'm that unreasonable.
Dr. Laura: I'll tell you why, because when you and I were kids, nobody's parents were anything other than how you want to be. So there was very little reinforcement for the arrogance of adolescence.
Carol: Yes. Well, she has it, and I'm sure I've done it to her. You know, let her get away with things or whatever, but it's been a terrible summer and I can't wait for school to start. And I don't know what to expect.
Dr. Laura: Well, yes you do, because you're going to lay it out.
In this website, it explains that "lay out" means to spend money.
But, I think that it isn't used in above context as to spend money for "lay it out". I think that is to plan.
so in last sentence, I think that it is to execute Dr.Laura's advice for Carol. ("you're going to lay it out" )
I wonder whether my thought is right or not.
It means to explain something in detail:
to plan or explain something very carefully and in great detail[;e.g.,] Plans for the ceremony were laid out so well that everyone knew what they were to do. Let's review the points one more time before we lay them out for the press.
