That argument held sway with me for a long time, but not anymore.

Our kids get a decent amount of socialization through all the activities they're involved in, and when other kids find out they're homeschooled, their response is more often genuine surprise rather than "Oh, that figures."

The idea that kids learn social skills best by being thrown into a rigid, institutional environment surrounded by hundreds of other kids whose social skills are also far from developed is kinda silly, though. It's like saying criminals will reform themselves best by surrounding themselves with lots of other criminals.
