H and I have chats while he is on the swing. The school next door to us has a very annoying security light which flashes on and off all night. It is now a very valuable and useful night time light for us because the swing is right next to it.
Last night's discussion touched on maths. I want to buy maths text books and he explained carefully to me that he likes autonomous education. So I counter explained that my plan was to have a well stocked maths shelf which he could ignore or read privately when I am not around.
I think he can spot mission creep a mile off. I very much hope my mission is not about to creep and the books will not turn into weapons in a household maths war.
