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.
The parents at first allowed her to go to Catholic school because the public school in her area was academically & socially bad. After she'd been in school awhile, the parents decided they wanted her out - not because the school was bad, but because they needed her to "help around the house." They announced there would be no more money for tuition, so she went to work herself to pay for it. When she was 18 she left home and finished school on her own.
