Two years ago K first met Rusty and was rather scared of him. A year ago
she met him and they both decided the other was wonderful. So when grandma Rose was about to visit to Claire (and more importantly Rusty) K insisted on coming along.
She played with Rusty for two hours, paused to eat lunch with us grown-ups, and then carried on the games. (The extra was taken a few seconds after the main.) Finally we all went on a 6 km walk where she looked after Rusty all the time.
Once K went home Rusty more-or-less collapsed in an exhausted heap, and I'm reliably informed K did the same thing as soon as she was home.
