Being a fellow European with 'skolplikt/oppivelvollisuus' and one of the best education systems on the planet, I have also wondered why. I don't think homeschooling should be illegal, I can think of a lot of kids who would benefit from having the opportunity to study in a familiar environment with a 'teacher' that can focus only on the needs of that pupil. But there should be most definitely be a nationwide curriculum that everyone has to follow.
When I was young, there was a god with infinite power protecting me. Is there anyone else who felt that way? And was sure about it? but the first time I fell in love, I was thrown down - or maybe I broke free - and I bade farewell to God and became human. Now I don't have God's protection, and I walk on the ground without wings, but I don't regret this hardship. I want to live as a person. -Arina Tanemura
