Can you pick up some butter?

My daughter called me at 4.30 asking if I could pick up some butter on the way home, as she needed to bake some cookies for school.

No problem - would you like some chocolate chips as well?

No, she said, I'm not doing anything elaborate. Just biscuits.

Fast forward to half past ten this evening. She's decorating every single one of the 30 biscuits she's baked with either Christmas red or Grinch green (a future Farrow and Ball colour?) and an array of dots and squiggles, faces and borders... 

Nothing elaborate she said!
