I'll assume you're not deliberately trolling and bite on this one...
Yes, that's right - when you home-school your children the only people they have any interaction with is their own parents. And even that is only to take them out of the cupboard at feeding time.
You would never, for example, meet up with other people who also home school and go on field trips for example. You wouldn't sign them up for after-school type classes such as dancing, music, and sports. You certainly would never take them to places such as a museum or art gallery. You certainly wouldn't hire out a hall on a regular basis and invite people like
professor kaos to come and visit.
I feel that a single highly-skilled teacher looking after 25+ children of wildly differing abilities is really able to tailor make each lesson to suit all their needs, and I don't see any scenario in which an individual child would either be bored, or feel left behind. Class sizes has never been a problem for teachers and never will be. I certainly don't remember feeling by turns frustrated in subjects I was poor at and bored in subjects I was good at.
