Well, I tried not to learn anything that day, but I learned that it was Learn Nothing Day. Maybe not a joke, but I laughed nonetheless.
Offering just a personal musing: as unschoolers, we are often in a position of defending ourselves and our lifestyles. What do we point to? The things that schooled society currently values: I talk about impromptu science, discovered math, learning to read by themselves. But if you asked me what was really important in my children's life, I would not start with these things. These are the things that justify my unschooling to the greater public, and to my more insecure (public-schooled) self. My secure unschooling self finds joy in mud between the toes and feeding huckleberries to supremely calm little chickens, watering the nursery, even at 5 and 7yo, not just 2 and 3.
I'm glad my girls do learn the other stuff, but I see the point of the Day: we say we are learning 24/7/365, that there is no division between real life and learning.
Well, it's about time we unschoolers take a summer vacation....... really immerse ourselves into unschooling. (Or, nevermind, screw "unschooling", just life.)
It is not necessarily a lifestyle to learn ABC in a different way.... it's just life. It might be good to just let go of these internal justifications and live it. (Warning: seemingly superior statement ahead-- no offense intended) Just like enlightenment, thinking about it kind of gets in the way.
