Dave inconsistently calls Roxy by her name or “mom” from sentence to sentence or even within the same sentence. Roxy thinks it’s “max adorbs.”
Rose will sometimes jokingly call Dirk “father,” especially when he asks her for something and she’ll respond with, “yes, father dearest.” Which annoyed him at first, but now he plays along with some silly fatherly dialogue like “I don’t appreciate your tone, daughter. None of this back-sass or it’s off to bed without supper.” And both of them play it completely straight leading others to wonder if they’re serious or not.
Rose will do it constantly if Dave’s around and Dave hates it because they always drag him into the mix. Rose will be like, “Dave, you mustn’t use such foul language in front of father.” And Dirk’s like, “yeah, I’m super fucking offended. Why can’t you be well-mannered like your sister?” And Dave just lets out the biggest groan. Roxy loves when she gets to play along. “u better listen to ur hunkilicious mom and dad, kids. and maybe you’ll be as hot as us some day” And Dirk takes the dadly pipe that he didn’t have a minute ago out of his mouth to say, “damn right.” Dave pirouettes off the handle through the open window.
