The question that that raises is what the end result of their being clones of the failed experiments that are John and Elly is. The clue to this is the sequence from which I derived the title to this essay. You see, a few years ago, Meredith was giving Robin the Penetrating Death Glare because she was forced to share something with Stinky Baby Brother despite her never having been consulted on the size of the family. This suggests that neither parent has any problem with stupidly pitting the children against one another to keep them from teaming up and somehow or other overthrowing their parents. This would be bad enough in and of itself were it not for both parents having severe problems with the very idea of girls having any sort of strong opinions. Mike's belief that Elly's opinion means his doom and Deanna's dread of Mira's free will mean that most of their mental capital will be spent suppressing Meredith's freedom of expression so as to save themselves from her tyranny.
Hmmmm. This seems like the excuse Jim and Marian gave when they kept Elly on a tight leash while letting Phil run hog-freaking-wild. Mind you, the current failures will probably pay lip service to modernity by saying that while both of their children are equal, it's just that Robin is more equal, the result will be the same: Meredith Patterson will spend her life jabbing her finger in the air like a lunatic while convinced that her husband and children are trying to keep her chained to the kitchen. Eventually, she'll yell that she quits motherhood because her daughter politely says "Not yet" when a craven "Yes, mother" is expected.
