You've got to show her who wears the trousers. Women have been taking liberties over the past 20 year or so - call it 'women's lib' - or Whatever. Make a stand - you don't have to actually chin her - just a quick back-hander.
She'll cry a bit - but you've got to be tough. Eventually she'll see reason and you're back on top, see.
If you've any qualms about this method give yourself the benefit of a couple of cans of good strong lager - the old dutch courage.
