These various aspects of Catholic socialization are hardly ever addressed in a public school classroom, and may have to be marginalized in many Catholic classrooms due to lack of time. Yet these are the very principles that demonstrate to our children who they are in the Church and how they are to corporately love and serve the Lord. Notice there are no scripture passages dealing with the sin of shyness. It is the institutional setting of age-segregated socialization that is an artificially narrow form of socialization. In the home, the neighborhood, the marketplace and the Church we find a mixture of ages.
Home is the best place for learning good manners and polite conversation.
Here respect for others can best be enforced. It's not that our children will not need to grow in these areas-of course they will. Children who are formed socially in an age-segregated institution tend to become less and less interested in playing with children that are younger than themselves. Whereas home educated children tend to be comfortable with a much broader range of ages. They also speak comfortably with college students and other adults, including elderly folk.
