A four year old boy is laying in bed looking at his ceiling.  For as long as he can remember he has always wanted to be in a circus.  Tonight, like most nights, he is dreaming of himself flying through the air doing all different kinds of acrobatic moves with his partner.  She is his best friend he has had his whole life.  She lives next door to him and they often go visit the circus, in real life and in their dreams.  That is their dream for their life.  To always be friends and to be in the circus together and when they get old to retire together.  Always to be together.  But as he falls asleep the last thing he sees is not them in the circus but the soft glow of the light of his night light above him.
