"What the heck do women want?"
One or more of the following:
a) Everything.
b) They have no idea whatsoever.
c) Whatever is the opposite of what they have right now.
d) Ever see the vision sequence between Frodo and Galadriel in Lord of the Rings? Yeah, kinda like that.
e) "To be happy/to be loved" - see 'a' through 'd,' above, for what this means 'as applied.'
On a more serious note, ol' Kay is apparently blind to the idea that what she sees as women being ever-so-adult is actually exactly the same thing the young men are doing, subbing two hours shopping for two hours gaming, which are equally-immature pursuits (not that I have a problem with doing immature things, but let's call a spade a spade here). It has the net effect of changing the dynamic at least as much by taking the female side of the equation out of play on that whole family-formation failure that she seems to be bemoaning. I don't know anything about the woman, but it reads like a biological clock-driven rant about why it's all men's fault.
