“Before you take me up to bed, will you tell me a story?”

“Do you actually need me to take you up to bed?” I asked the boy.

He thought for a moment. Then, with intense seriousness, “Yes, actually I think you do. It’s because of, I’ve finished my homework, and so it’s my bedtime, and I am a bit scared. Not very scared. Just a bit. But it is a very big house, and lots of times the lights don’t work and it’s a sort of dark.”
