Every day when I pick Max up at day care, as we're making our way to the car, I ask him if he had a good day (Always “Yes!”) and what he did that day… his go-to answer to questions has always been “I don't know”
Reading a book, he'll point to something and say “What's this?” and we say “What is it?” he responds “I don't know!” then thinks a moment and comes up with the correct answer, be it a color, a shape or an object.
So today, I picked him up and asked him what he did today. His answer, for the first time ever! Was an actual answer! “I played books! I played cars! I love cars!”
He spends a lot of time telling us things he loves; people at day care (both the provider, Michelle, and the other kids), foods, when he's eating them (“I looove french fries!”), things mentioned in books we're looking at (“Stinky socks! I love stinky socks!”
It's a joy to have the time in the car every afternoon, as he becomes more and more of a participant in our conversations; I know I'll miss this someday, several years from now, when I ask “What did you do at school today?” And the answer is a sullen “Nothin'”
