If that's the worst problem of home-schoolers, I'll gladly tolerate it. It beats being beaten into submission, conformity, non-participation, and doing the minimum necessary, which is the mindset of the typical factory-school attendee. That's even assuming there's no brainwashing or undermining of parental authority.
Perhaps you were paying homeschoolers a backhanded compliment. If so, sorry :->
Perhaps ... perhaps I'm 9 months pregnant and surrounded by verbose, opinionated kids who don't stop talking even in their sleep. And did I mention they know EVERYTHING?
I suppose this isn't an issue with some homeschooled students ... it could be genetic.
