Sarah: "I don't like the dark, it's scary. Turn on the light for me please?"Sam: "C'mon sweetie, there’s nothing to be afraid of in the dark. Sometimes darkness is a good thing, Like, when you want to go to sleep."Sarah: "I could go to sleep with the light on."Sam: "When it's light, you can’t see into a place that’s dark, but when its dark, you can see what’s around you much better."Sarah: "Really?"Sam: "Really. So if there’s monsters or bad people around, you can see them. And if you're in the dark, they can’t see you."
