Knowing she shouldn't write on the vertical blinds, Laurel apologized in her graffiti.
We got Laurel a wall calendar a few months ago after she expressed an interest in having one to write on (I have a calendar in the kitchen that I write on daily) and she's used it diligently to note things she finds important. I guess she *really* likes writing on vertical surfaces, because when I went into her room a few minutes ago to give the windows a quick swipe, I noticed she'd written on the vertical blinds.
She knows not to write on non-paper surfaces and must have been thinking about it as she did, because she wrote "I'm sorry" on the blinds in crayon.
(And she'll be the first to tell you that a little 409 cleaner on a paper towel and some elbow grease took it right off.)
