Some people have the opinion that homeschoolers raise their kids in a bubble. And I suppose that some homeschoolers do. Let's just not go overboard and think that it's the majority, or even that it's the norm. Statements like that are unfairly subjective.
In our family, the truth is that my kids "get out". They have weekly p.e. classes and weekly co-op (for 8 weeks each semester). They play several days a week with neighborhood friends, attend a few birthday parties a year, interact with kids and adults at worship weekly, and enjoy time with their grandparents a couple times a month. These kids get their social strokes. No doubt about it.
Their mom, on the other hand -- not so much.
Gotta work on that.
