It seems simple to me. If you're trying to listen for a sound, you have to stop talking and be still.
Some people want to see unschooling while they're still teaching and putzing and assigning and requiring. They have to stop that FIRST. And then they have to be still. And then they have to look at their child with new eyes.
If they don't, it won't happen.
