I have often wondered like a few here about nadin's mental health. Word salad and a few other traits that she does show are pretty consistent with schizophrenia.
I think with the right medications and a liberal application of a rubber room might just cure her.
Allow me, madam, please, to be Sigmund Freud for a minute here.
People who are considerate, thoughtful, of their audience take the time and trouble and care to put forth their message in the cleanest, clearest, manner.
People who are slobs in expressing their message don't care about their audience; in fact, they actually have contempt for their audience.
I don't think it's any secret to anybody but the primitives, that nadin loathes, detests, her fellow primitives; doesn't think nicely of them at all. So instead of feeding them her finest cuisine, she feeds them shit.
