The reason that I mention this is that it seems to me that insane angels are why Marian did certain things. The first thing is turning Jim down flat when he wanted a dog. Her good angel told her "You work all the time and it wouldn't be fair to the pooch; besides, animals in the house on purpose might not be good for kids because one of them could hurt the other." Her bad angel remembered that her dad loved some filthy mutt more than he loved her and if she hated something, she'd be damned if Jim and the kids could enjoy it. Since she couldn't say that to herself because she didn't think of herself as having a vindictive streak, she probably sold herself the loonie fairy story Connie told about psychological warfare.
The reason I assume that Marian has a crazy angel is the reason she gave for shouting Elly down and never letting her win an argument and never letting her know she was loved. Her good angel feared for her loss of initiative and accepted that to get along, Elly must learn to go along. Her bad angel snarled that this was her house and it weren't no democracy and damn it, who cared about the kid's feellings, she deserved to win arguments for once. Her insane angel protected her from the knowledge of the bad angel and told her that a high-spirited two year old was a criminal dictator in the making who needed to be suppressed for the greater good of all mankind. When I read Marian's reasons for stifling Elly at every turning, I heard something: a grim shade of an infamous traitor and the spectre of an anthropomorphic smoked sausage declaring "Mission Accomplished." Too bad that Benny and Big Hot Dog are family friends.
