Turns out they did have homework, so there was a lot of scrubbing brush action, followed by some serious book larnin'. As I say, a nice day.
All of this came from my new book, "Wreck This Journal" by Keri Smith. One page is a target, with instructions to throw a ball, or something, dipped in paint at it. We keep three solid rubber balls around the house for just that purpose.
And the book - was my anniversary present! 15 great years, and he's clever enough to locate a wonderful present like this!
