BTW, I homeschooled my son until he was 13 yrs old. The only reason that I then enrolled him in school was that his Dad passed away and I had to work to keep us afloat. When they "tested" him, he was way above grade level and the school psychologist told me that she had "never met a more well adjusted child". That blows your theory away that homeschooled children are lacking.
The real question is though, can he put a condom on a cucumber in the proper fashion? If not, you clearly were not qualified to teach him.
