Wellll, we could headcanon that this family doesn’t do it or maybe she left for Canada and stopped, but surely she would have then remembered it from her childhood. So is it just a flub from Maca? That she then corrects mid-sentence?
Actually, now I’m on the side of it being written. As real as it looks and as minor a detail as it would have been, that’s what makes them laugh, which then segues into being interrupted by Lucho in the scene itself. So kudos to the writers and Maca, I guess?
