picture book

this morning on our walk to school, penny was making up songs.  mostly they were about things that we passed - christmas decorations, cars, trees, etc.  she told me that she had a couple of songs that she had written that i hadn't heard yet - for chanukah, for the fourth of july and for christmas.  then she told me that she had written some books.  picture books.  i asked what kind of pictures were in the books, and she said "naughty pictures".  uh oh.  i asked her to tell me about the pictures - what were they pictures of? "kicking, hitting, yelling, not being nice to friends...a book for naughty kids."  oh, ok.
