The theory once was: never fight in front of your children, and never kiss in front of them either. The result? A whole generation which assumed that passion in all its forms was a thing to be feared and hidden and that romance always precedes marriage but never sustains it.
This then is the eighth prescription for the recovery of a simpler and more sacramental life: make holy the space between you by showing simple affection. Let your children see you kiss. Let them see you embrace. Let them overhear your teasing, your gentle rebukes, even your well-intentioned jealousy. Domestic courtship reinforces the notion that people are together because they want to be together, not because it's the decent, practical thing to do.
