I once herd it said the difference between a man's mental reasoning and a woman's, is a man thinks solely of the result and a woman thinks only of the process.
A few examples are:
Marriage: He wants to get married, she wants to have a wedding.
Trip to the store: He wants to go buy it, she wants to go shopping.
Sex: Self explanatory.
The guy who said this was really close to figuring it out.
