"It's pretty good, but you mostly write about the girl, and you might want to write more about the brother, because he's pretty funny. Also, something should go wrong, so the story will be exciting." And, "Would you like me to write up some more suggestions, and ideas for how she can be naughty?" And I said sure.
A little bit later, Kavi brought me this:
Page 1: General suggestions:
- talk more about her brother
- have the "naughty day" go wrong
- add a picture of the family with the girl in front
- have the brother need the opposite of a "naughty day"
- her brother gets a restraining order
Page 2: Ideas for bad things she does:
- she throws mud balls at the neighbors
- she cheats on homework
- lie about school grades
- she ignores her brother
- she colors all over the piano
- she pranks her cousin with a water balloon
- she sneaks out of the the house
- she composts plastic
Asking your child to critique your work is a bit harrowing.
Also, those ideas! This may not have been the wisest book topic ever.
