I sat observing and listening, feeling very impressed as Dale rattled on and on to a grown-up family friend all he knew about space.
I had no idea he knew so much about gravity, and the lack of it, and the hot sun, and, and, and.... the information just kept spilling out.
The kind friend (who happens to be dad to a home-schooled family) winked at me while saying to Dale, "Wow! You must have a really great science teacher!"
"No," came Dale's immediate reply, "I read it in a book."
Next week's lesson: not blowing mom's cover. ;)
