I homeschooled for 12-13 years (if you count the preschool year before kindergarten.) I was also involved in several groups, and helped run one for awhile, so I did meet a lot of different homeschoolers. In the interests of fair disclosure, all my children are in public school now, where they are doing well.
I have known at least seven teenagers who wanted to go to school; some wanted to go to private school and a few wanted to go to public. Most of those were able to convince their parents to send them to school.
One girl had to get a job at 16 and pay for her own tuition, because her parents objected to her going to school. Two other girls were kept home by their parents. To my knowledge neither of those girls has gone to college, moved out, or gotten a job (and they are now beyond high school graduation age.)
The person who started this thread may be a troll. So it goes. But my experience with homeschooling has led me to meet *all* kinds of families - those whose children were prodigies and excelled phenomenally at very early ages; those who were just average, and those who were really dysfunctional, and involved in some major power struggles with their kids. Just like other families, in other words.
Ok, so there are a few. Most will convince their parents to send them. I am laughing at the idea of thousands and thousands of homeschool parents locking their teenagers in the attic to prevent them from going to public school.
Most of the kids I've known who want to go back to school either do so because of peer pressure (all their friends go) or because they were yanked out too late and can't readjust. I'm sure you're doing what's best for your kids but - why on earth did this girl you know have to earn tuition? She didn't want to be homeschooled, but didn't want public school either? That just seems goofy.
