My daughter is 9, we've been unschooling most of her life.
I have, as someone above me said, "mini freakouts" about her socially, mostly at her lack of "street smarts" in the social sense. Among unschooled or eclectically homeschooled kids, she's fine.
It's among traditionally schooled, especially public schooled kids, that she tends to get in trouble. Public schools here are rough socially, very hierarchical and almost a "Lord of the Flies" environment. DD has few skills to cope with that mentality. She trusts and likes adults, she's a very poor liar (it's comical the few times she's tried, usually at the behest of older children), and she doesn't have the reference points to understand why these children lie, steal, bully, manipulate.
As she grows older, it's happening less and less, but when she was younger, she would often get roped in and become (mostly) unwittingly complicit in their wrongdoings, because it just never occurred to her that they were lying or intentionally being bad. Nowadays she's grown wiser and has the developmental maturity to understand that most children come from environments, school and home, where lying, manipulating, power struggles, bullying and deception, are not only commonplace but necessary. She's not indiscriminate with her trust any more and takes the time to think about why she's being asked to go along with things, what others' motivations may be.
I like others here have had occasional outbursts of wanting to enforce schoolwork to make sure she's "on track." As much as I hate it, I don't think my inner school-marm is ever going to completely shut her ugly face! I've resisted temptation to assign work, but I do keep curriculum in the house. Singapore, those big colourful all-in-one workbooks, Spectrum, little things like that. I consider them just another resource. And she actually likes some of them, she does it when she's bored or takes a workbook when we have a long car trip ahead. That it's an option for her is enough to satisfy me and shut up my inner school marm! The rest of me just has to have faith that if she wants or needs to learn soemthing, she will find a way, whether it's through those workbooks or not. And so far that's exactly what's happened, she always finds her own way and a way she is happiest with.
