Louisa nodded out of habit but added a "Yes." when she remembered that he couldn't see the expression with her behind the canvas.  There was something about the set of his brow that wasn't sitting right with her and she couldn't quite place why.  She took a few steps back to regard her work at a distance, her head tilted as she puzzled over it. 

"Well, when he's present at least.  They do like to wander sometimes."  She glanced repeatedly between him and canvas with a frown of concentration, trying to find where she went astray.  With a cluck of her tongue she set her brush and palette down and reached for her wand.  She muttered a spell that made the canvas rise off the easel, flip upside down, and settle back where it was.  "And I wouldn't believe them if it looks like they are sleeping - I'm not convinced they actually can sleep." She regarded the flipped image it with her arms crossed over her chest, only paying half attention to the conversation.  "I'd say its best to assume there's always someone there listening but not always paying attention."
