I think it's psychological - I wouldn't be surprised if on a psychiatrist's couch, Nads once confessed that she believes her parents never encouraged her by shining praise on her, just criticism- and now she has this unfulfilled need to have her artwork on up on the proverbial fridge.
Consider what
probably happened.
Grandparents, Jews in Poland during the 1930s, manage to flee to another place (in this case, Mexico), happily saving themselves and their small children, one of which is a parent of nadin.
Such terrors are lifelong, and can be passed on.
The parents of nadin, or at least one parent of nadin, with childhood fears still impressed in the mind, bring little nadin into the world circa 1964, and their driving impulse is that she
must survive.
Kudos to the grandparents and parents, who've surely since found favor with God.
But what went awry here was that the parents did two conflicting things; on one hand, they sheltered little nadin from the vicissitudes of life, as if a hot-house flower, but then on the other hand demanded that she become strong, tough, so as to survive.
Didn't nadin once claim to have served in the Israeli Defense Forces--if so, it's probably credible, and a credit to her.
But on the other hand, nadin isn't as tough as she wishes to be seen to be; she's hardly the model of self-reliance, depending upon hubby's money to support her habit of shooting off her mouth. As with the occupoopers, all of her rantings and ravings against the "system" are financed by that very same "system" (in the sense of giving her the luxury to rant and rave without having to spend time working for a living).
