Perhaps so that we can answer questions like "list all the grandmothers".

If we're storing mother<->child relationships, and the knowledge of the 
existence of a particular relationship resides only in the objects 
involved in the relationship, then we have to examine all of the objects 
that may be part of a relationship.

If the relationships are stored centrally, then we can start our search 
with the relationships and work from there.
