I think that the Halloween costume brouhaha can serve as a nice example of Elly assuming that the prosaic and benign is the apocalyptic. This is because she and Annie whine piteously about how the prospect of nuclear war has so enraged and traumatized their innocent children that they've given up on fun and happiness and can now only be scary monsters who reject everything. The only rational response to such whimpering, ignorant, panicky and ludicrous no-think is the question "How long have you two imbeciles been smoking crack cocaine?!" Only a long-term history of exposure to brain-melting chemicals can explain stupidity that profound without resorting to speculation as to whether she and Annie are missing key chromosomes.
The end result of her living in a world of unreasoning, unbelievable and idiotic fear is that she witlessly robs herself of any sort of peace of mind. When she bewailed the fact that her impatience and lack of tolerance made it seem as if her time with her children zipped by before she knew it, Elly lost sight of the fact that her mindless panicking over nothing at all was an even worse thief.
Sadly, this theft is one she and her fans approve of. For reasons that I'll get into tomorrow, the non-event is supposed to be a threat so dire and horrifying that we don't actually need to have it explained to us.
