It is evidence of too much government formal schooling.
Being able to use bled, pled, pleaded, and sneaked correctly is evidence of homeschooling.
Yeah! Rejoice with me, for of my one son's ten home-schooled children one young man is graduating from high school (the fourth to do so, this evening), while his older brother is graduating from engineering school with honors almost simultaneously.
Pray for my other son's fourth child (of five), my granddaughter, who last evening graduated from public high school--a child from a broken home.
Two of my daughter's four children are in public school yet, and two are attending college. All four endured Montessori/public school, but with much less lustrous experience than their home-trained cousins.
I've seen the story from both sides, and know anecdotally that well-done Christian home-schooling wins, hands down.
