A few days ago I saw WZ dig out two cardboard boxes from a cupboard and then started pulling out some books from them. Then he'd attempt to read it but of course he couldn't understand everything yet. The box was interesting, it was more like a binder than a box. And they held 6 books each.
WZ can't actually read them yet, but he can memorize the titles based on the pictures of the books. Even though of course, these are simple picture books with giant illustration on one side, and words in big giant fonts on the other side.
When I saw WZ retrieve the boxes I already knew what the contents were. You see, these aren't WZ's picture books. These were MY picture books. The memory is faint, but I do remember that the books were kept in the box previously when I was... I don't know... 3? 4? And of course, now WZ inherits them. Hopefully he doesn't completely destroy them in a fit of rage or something.
The other main treasure that WZ will inherit will be something I present to him when I realize he wouldn't shallow small plastic bricks. :P
