When a couple have chairs, the smaller guest chairs are added, because they come and go. The bread is our physical needs, and communication serves as the utensils. Love is the dinner bell which calls us together. A dining room would be incomplete without all of the necessary items. We can make vows, but without the table, we focus on our individual laps.
Children are additions to the family who are fed until they can feed themselves.
For them to remain or become the center of the marriage, it would be like the continual adding of chairs without ever emptying them. If the chairs are not eventually vacated, the marriage partners either have to give up their seats and rely upon the children to fulfill the marital commitment or discard the table and purchase a new one in whichthe marriage is significantly altered or, worse, abandoned. Neglecting physical needs is like dining without bread. We continue to starve and eventually either die or find our bread elsewhere. It is tough to eat without utensils.
