I have days when I feel like everything I thought I knew turns out to be wrong. Like when I talk to my five year old about dinosaurs. Or my six year old about math.
But, mostly, I have to say, my fancy book learning, for all its shortcomings, has held up pretty well. I’m usually reasonably confident in my understanding of life, the universe and How Things Work. In fact, I’d say that my fundamental beliefs have remained virtually unchanged through adulthood. I guess I’ve been lucky that way. Or sheltered.
