In the book The Giver, what are some traits of the mother and father?

Jonas is raised by his mother and father.  His father is a Nurturer, who cares for babies.  He is a cheerful person and he is playful with his children.  He is the more nurturing of the two parents, which may be in part because of his occupation and aptitude.  His mother works for the Department of Justice in a high level position.  She is more serious and rational.  

Both parents are kind to Jonas and his sister, Lily.  When needed, they offer comfort to their children with small gestures, such as hand holding.  However, there is a lack of warmth in the family.  The relationship of the parents is one that is not romantic because of the medications taken to suppress the "stirrings."  Their relationship is practical, and the main purpose is to raise their children.
