A: It's time for bed.

B: I'm not ready to go to sleep. I'm not tired.

A: It's quite late, and you have an early day tomorrow.

B: I'm not going to be able to fall asleep.

A: Why don't you try counting sheep?

B: I've tried that before. It really doesn't work.

A: That's beside the point, you still need to go to bed.

B: Why can't I just stay up until I fall asleep?

A: If I let you do that, then you're just going to be up all night.

B: I promise I'll go to sleep soon.

A: No, you're going to sleep now, so good night.

B: See you in the morning.
