The reason I was homeschooled? My dad is a bit of a nutjob and was paranoid about the government. Not to mention, he was severely controlling.
Thanks to homeschooling, I'm socially awkward, anti-social, have issues relating to people my own age (and people in general), have issues in higher levels of math (what happens when a parent who only had pre-algebra tries to teach algebra 2), and a nice other host of issues that I won't go into.
Sure. I was in camp fires and I played with the other kids in my housing development. In campfires, I was treated as an outsider and picked on because all the kids knew each other from school. My "friends" at the housing development were not only several years older than me, they borderline abusive because they saw me as a smart allelic and I put up with it because I was so starved for interaction with people in my own age group.
So, I reiterate, don't homeschool your kids. It'll screw em up.
