Here’s my psychological take on the situation:
Women are more greatly affected by small gestures. They feel loved if you help them with their coat, hold a door open, and put the seat down. Men, on the other hand, tend to not care about these things.
If a women is really angry about the state of the toilet seat, I’d suggest that she has ‘issues’ with the relationship in general that she needs to deal with. Perhaps she doesn’t feel loved, and every time the seat is left up it reminds her of that.
On the other hand, she may just be a self-centered cow.
I try to remember to put the seat back down for my wife. But sometimes I forget (I do my best thinking in the bathroom, which means I may not be paying that much attention to all the details). In ten years of marriage, it has NEVER been an issue. Perhaps that’s because I express my love for my wife in many other ways on a routine basis, so the state of the toilet seat stays in the realm of the trivial where it belongs.
You hear stories about marriages that break up over stupid things like leaving the cap off the toothpaste. I would suggest that if someone REALLY wants a divorce over toothpaste control issues, there are bigger, more important issues that need to be dealt with.
But some women have taken this way too far. The ‘falling in’ argument is ridiculous. How would you women react if your husband came flying out of the bathroom in a rage because he just pissed all over the toilet seat because you left it down? Let me guess: You’d think he was an idiot for not looking, and you’d be offended that he would get so mad over your mistake, when his was much larger.
One more comment: The best way to get a man to do nice little things for you is to not demand them, and to do things for him that make him love you. If my wife started an argument every time the toilet seat was left up, I’d probably stop putting it down at all until she was more reasonable about it. I’m not a slave, and neither is she.
