The older Fireflies told the younger ones that they should get all the sleep they could during the daytime if they were to flutter and frisk all night. Most of them did this, but two young Fireflies, who cared more about seeing the world than they did about minding their elders, used to run away while the rest were dreaming. Each thought herself very important, and was sure that if the others missed her they wouldn't sleep a wink all day.
