So my daughter recently turned 4, she's far far ahead of other children her age when it comes to communication. She has no problem walking up to anyone she happens to meet and striking up a conversation. Several weeks ago she asked me why most of the adults we see are always in a hurry. I explained to her that most people have jobs during the day, feel like they're behind, etc. So for the last few weeks she's been stopping people, introducing herself and asking them what their job is.
We've spent a lot of time talking about the very rare occasions where someone is rude or not willing to talk to her... She's already learning to notice the broken people...
That being said, she's voracious when it come to educating herself. She's not quite able to pickup a book and read it, but she's getting there. My wife and I are scrambling to sort out the home schooling thing since we don't want to send her into the mental mugging that is state schooling. Since she's socially fearless and curious now, I can't imagine that she'll somehow become socially deficient through being home schooled. Even if she becomes a 'social outcast' - I don't think she'll really be missing anything. The most broken people will simply avoid her because she'll scare them on some deep level and it will be that much easier for her to find those people who's are willing and able to connect with her.
