There seems to be something of a double standard in the Foobiverse. Women we are meant to approve of are allowed to criticize their husbands all day long and the husband is just supposed to take it. (This, of course, does not apply to evil career women or evil mothers-in-law, of course. They should shut up because they don't Know Their Place.) The husband, on the other hand, is not ever to suggest that his wife does anything that annoys or even mildly disturbs him; that, you see, is a hateful thing to do. She cannot be a victim of his oppression in the least; either he says that she is perfect in every way or he's a monster. The end result of his being cowed into submission is that while his own character defects are eroded away by time, hers are reinforced because they are never addressed. We've seen how John became less dickish while Elly became worse and worse over the decades. We can, with noses firmly pinched between thumb and forefinger, imagine the end result of never admitting they're wrong will do to Liz and Deanna.
