On the flipside from constant nagging and picking at what you do wrong is the other, equally scary extreme: she can't even be bothered commenting. Any time men get together, you'll hear the same old story: my wife is always nagging me, or my girlfriend gets angry over the tiniest stuff. I forgot to be at the birth of our baby and she was weirdly furious - that kind of thing.
But try to imagine the opposite, if you can. What if she didn't care at all? What if she didn't even raise an eyebrow at your antics, or just stayed quiet when you came home drunk and pooped on the floor? In a way, the only thing scarier than an angry woman is a silent woman, because that means her mind is on other things. She's probably already moved on.
