This reminds me of a conversation with my FIL's wife. She is generally very supportive of homeschooling, but she told me once about how my BIL really should continue his education, but he is unable to sit still through an entire class period. She told me I really should put DD8 in some classes at some point to prevent this. Of course, a little while I after the conversation, I really thought about it. BIL was in public school PK - 12 so being in classes didn't help prevent that problem for him. Why would that work for my child?
There are aspects to learning style that are going to be there whether someone is home schooled or public schooled and I think the preference for one on one v. group is largely one of them. Someone will adapt somewhat to the environment they are in daily, but the inherent preference will remain, IMO.
I love the post about trade-offs. That is so true and something I need to remember as a response to those that want to tell me all the opportunities my child is missing.
