I know this has been brought up before, but I knew some home schooled children at both ends of the socialization spectrum. One family was very active in church and public school sports, probably scouts, the other was not. They need regular interaction with kids their own age and probably of different ages. The awkward home school kids had no problems talking to adults, but were very awkward around kids their own age. This might be an issue of let kids be kids?

I know the "sports" home school kids now as young adults (1 married, 1 out of college) and they are very social and quite the comedians. Unfortunately I do not know the other family as adults.
