My daughter has become proficient in bedtime stalling techniques.
The most effective one of all, though, is, "Sky?"
We go out front, sit on the steps, and look at the sky, and we talk. We talk about our day, and what she's going to do tomorrow. We talk about the moon, and how bright it is, or if it's hiding, we wonder where it might be. We talk about the color of the sky, and the weather.
She's got me pegged.
