Pencil on plasterboard!
I bolt up, and sure enough, there is Anabel scratching away on the perfectly white walls in my bedroom. I didn't even know she could hold a pencil, let alone draw with it! As I took the pencil from her and assessed the artwork, she looked up at me and smiled a smile that I know only too well. It's the smile only the mother of a ratbag will fully appreciate.
All I can say is, thank goodness for magic wall erasers, which I now keep a supply of in my laundry cupboard.
Gee, let me guess where she learned how to do that.... Ugh, I'm so in trouble....
