If I want my kids to feel school atmosphere socialization I will personally physically kick their butts while calling them vulgar names while my wife stands around and berates them in belittling ways.
That should be enough school socialization to last them for another year or two.
Otherwise, we continue to participate in homeschool functions on a weekly basis. Field trips, group gatherings, and other functions like church. Our kids enjoy the many church sports options offered and seem to be functioning quite well without the unruly influences of some of the public school children. Everywhere we go, people compliment how well behaved our children are and I don't see any reason to stop homeschooling in the near future.
I drag my kids into the bathroom, beat them up, and take their lunch money once a week.
Now, I will admit that my daughter is deprived; so far she has only had two cousins make rude comments about her chest, but since that does not take place on an ongoing basis, I suppose she is being deprived of an essential element of socialization. So, I guess I am a bad father for depriving my daughter in this way...
I'd sure like for them to give a good definition of socialization.
