This probably deserves it's own thread, but why are women like this? My wife is not a very good planner, often over-books herself because she forgets half the stuff she has planned, and always makes last minute plans or changes. And a lot of her girlfriends are like this too. But I know very few men who have this fly-by-the-seat-of-their-pants mentality.
Clearly women are wired differently than men, but I also wonder if sometimes there's a bit of laziness and entitlement also going on. Like they want to be free to do what they want, when they want, and they expect us (the guy) to figure out how to make it work. Which we usually do, because let's face it, what man isn't willing to put in the extra effort to increase his chances of having sex?
