Home schooled children are known to be vulnerable, withdrawn, naïve, easily led, fragile, and socially awkward: and for good reason. They've never had the edges bumped at school or encountered any kind of negativity or social adversity. I get the urge to shelter little darlings from all nasty things, but it produces really clueless, vulnerable young adults who have zero cynicism, real world experience, street smarts, or emotional resilience. Only playing with children you like is a recipe for disaster. I'm not so concerned with bad parents as what total social isolation from the world means. A few get togethers a few times a year with other children for an hour or two is not enough.
