You went to the circus already. It was great. Then you had to go home. That was bad. You stayed up really late so you can run away and see it again.
You will all play children up well past their bed times who have run off to see the circus. At night, the circus changes and danger approaches. But you really want to see the clowns before you go home. Also you have crazy powers brought on by your lack of sleep. Pretty cool, huh?
