The most common form of homeschooling is, I believe, in the form of co-ops. Where groups of parents get their kids together in class room like settings to teach them together. They don't go to school, they might meet at a church, or library or a home, but they are socializing. I know people who homeschool and between church, youth fellowship, co-op classes, fencing, swimming, basketball, neighborhood kids, family, etc. they have extremely active social lives.
