The issue is not that she is making unreasonable demands. The issue is she's making demands unreasonably. Even though what she's asking for may seem trivial, she's talking divorce over not getting her way.
He has asked us to believe that he is in the wrong and that he is constantly screwing up... Why shouldn't we take this man at his word?
Because many of us have "been there, done that," been raised by single women, and/or recognize the manipulative camouflage of "I want you to help me clean, but I get to say what's clean enough."
Most men in our culture have been so thoroughly indoctrinated it never occurs to them to question female assumptions. Men have had "put the seat down" drilled into them so thoroughly, it seldom occurs to them to wonder why women aren't suppose to leave the seat up.
If that's where you set the bar, you're just looking for a fight; and real men don't fight about the positioning of the toilet seat.
(The real reson they want it left down is this: If you leave it up, they might, absentmindedly, fall in when they try to sit down...possibly even injuring themselves...in fact, I would guess that 100% of the women who complain about the seat being left up have fallen into the toilet at some point in their lives. Now, as a man, I feel a certain desire for my woman to not fall in the toilet when she tries to use it, and as a result of this desire I always put the seat back down. I know. It's crazy, and I'm whipped.)
But I'll tell you one thing. When bedtime rolls around I'm usually rolling around too. Coincidence? You tell me.
