We always go to the library, or anywhere else for that matter, with the idea that we will learn something. The difference is that I don't go there with the idea of "teaching" something.
IMO unschooling is learning all the time, but rarely teaching. I say rarely because there are things that are taught. For example, when my Heidi (13)wanted to know how to crochet, I taught
her the basics and now she just comes and asks me when she wants to learn a new stitch or how to join something. (To be honest, she is much better at it now than I, and I often ask her to show me something.)
When my children wanted to learn a musical instrument, my dh taught
them the basics, but didn't give formal lessons, and they simply ask him when they need to learn something new. Now one dd is taking swing dance classes and another dressage riding lessons. These are things they want to learn and so we found people who could teach
Unschooling does not mean never teaching....it means not schooling. Do you see the difference?
As an aside, I thought I tell you that as I'm writing this, I've been interrupted about 5 times by kids with questions about connecting a beaded necklas, making a multiplication table, and how to keep the 2 year old grandchild out of the ferret's cage.
