I asked Younger Son if the lizards could spare him today so he could dog-sit as I knew I'd be at the hairdressers for a long time (making me look gorgeous is seriously time-consuming as well as finance-eating) and I wanted to do some shopping as well. When I got home he'd gone but had left me a note telling me what he'd done. He finished his note with P.S. Your hair looks nice.
I've trained him well.
