Anyone with good life experience know that maids aren't what their popular image suggests. Forget the silent, submissive young lady who never looks up and gladly obeys your orders. Hire one and your house is hers, and god have mercy on you if you anger her.
Did she mop the kitchen floor ? Your snack will have to wait. She just cleaned the toilet ? I hope you have a strong bladder. And don't even think of crashing on your couch. She hasn't vacuumed it yet.
Oh, she's a demon ? Same rules. It's all about savoir-vivre. Of course a French demon enjoys her fancy words.
