Those home-school kids often reside in “neighborhoods,” Father, where there are OTHER children with whom they bike, play pickup basketball, go sledding, or wander into the store to purchase candy. Those home-school kids often participate in Boy/Girl Scouts, non-school-related athletics, (it’s called Land O’ Lakes) and as a consequence meet and deal with adults who are not their own parents. Often they have jobs in retail; that’s not exactly “hermetic.” And in actually Catholic families, where there are several children, “negotiating” within the family circle is quite an exercise.
