Ahhh but you get what you ask for.
A small premie and parents pray for its life. Bargain with God, Let this child live and we will care for the child and love them come what may.
Child lives and thrives, for the first 3 years, then as it goes into it's mid- 6-8 years shows some disturbing dark side. Child becomes most odd, sets the cat on fire and seems to enjoy it.
The other children in the family seem scared of the child and no bonds between the child or it's brothers or sisters are ever seen. Child has no bond with either parent, but, the promise to God to care for this child is strong within the parents, we will care and protect this child.
These things happen, you get what you ask for.
