Does the mother ever leave the house?
I don’t think we ever see her outside. (Well, yeah, she's in the garden, but so are the kids. I mean the outside world, so to speak.) And at the end, when they’re looking for “Bruce”, it’s only the father who’s searching outside the property, while she remains “barking” with the kids. (Wow, what an odd sentence.)
I'd ask you to play House, but you'd be a weird example for our kids.
