If everyone helps to find a way to coax girls to sleep quickly?

You can say to her like this: "Why don't we change the game, such as guessing riddles, I'll tell a riddle, or have a brain teaser, you guess. If you can't guess, you can sleep and think again, think and fall asleep again, and announce the answer tomorrow "or try to say" tell you a joke, sleep if it's funny, and then you can sleep and recall it, so that you can fall asleep with a smile ". Anyway, you will try your best to persuade her to change her method with your eloquence.
