Please god if there is one, let this shebeast be lying for Jesus, for the sake of her daughter if nothing else.
Fucking seconded!
But if the bitch isn't lying... Talk about shooting yourself in the foot/cutting your nose to spite your face: from a purely self-interested point of view, she gains nothing tangible, and she puts a lot at risk. To gain the satisfaction of "punishing" her child for daring to have an opinion of her own, she exposed herself as the petty monster she is, and most probably alienated/disgusted not only the poor daughter, but also all the decent people in her family and acquaintances. She may well suddenly discover that the only people remaining in her social network are the callous assholes like herself, and those make a very poor support web in an hour of need.
LadyBuck doesn't seem to understand that as time goes by she's only going to grow weaker and sicker, and that it is simply not smart to antagonize a person who may well end up being the one making next-of-kin decisions for her. But even assuming that the daughter is too nice/manipulable to just dump the old bag in the worst shithole hospice she can find, jeopardizing her studies, and thus her professional future, is a very dumb move. Sure, maybe LadyBuck has a very good pension plan now, but the last few years have amply proved that things can happen to pension funds, things like Mittens-style vulture capitalists or out-of control traders, and then, even if the daughter is a saint and wants to help, it will be difficult if she's barely making a living with a dead-end, absolute minimum wage job because she had to drop out of college.
Of course, these are all just possibilities (my OCD makes me very good at imagining worst-case scenarios), but the fact remains that LadyBuck jeopardized all the positive things that may come from her relation with her daughter for the empty satisfaction of punishing her for not believing as she does.
