What do your neighbors think of your homeschooling? Is it more difficult for your kids to make friends? To get involved in team sports or after school activities?
If you ask most homeschoolers about socialization, they'll either laugh or get huffy. The general consensus is that it is *not* a problem based on the following:
1) Only associating with children your own age all day is not real socialization. With only 20 minutes of recess at some schools, this is far from a perfect avenue for learning to work and play well with others.
2) Homeschoolers are often out in the community taking classes, at a a co-op, or playing with other kids at the park. They interact with people of a range of ages in a variety of settings.
3) There are plenty of kids at school who are awkward as well, so obviously even traditional school doesn't automatically yield a well-adjusted populace.
