A: Shouldn't you already be in bed? B: I can't sleep. I'm really not all that tired. A: You need to get some rest, as you have to get up early in the morning. B: It's impossible for me to get to sleep right now. A: Just close your eyes, and try not to think. B: That really does not work for me. A: It doesn't matter, you need to get some sleep. B: How about I tire myself out, and then fall asleep when I'm tired? A: Then you're not going to go to sleep. B: Don't worry, I'll make sure and get to sleep in a little while. A: I want you in bed, right now, so sweet dreams. B: Fine. Sleep well yourself.
