The essential differences between a man and a woman

Let’s say a guy named Roger is attracted to a woman named Elaine. He
asks her out to a movie; she accepts; they have a pretty good time. A
few nights later he asks her out to dinner, and again they enjoy
themselves. They continue to see each other regularly, and after a
while neither one of them is seeing anybody else.

And then, one
evening when they’re driving home, a thought occurs to Elaine, and,
without really thinking, she says it aloud: “Do you realize that, as of
tonight, we’ve been seeing each other for exactly six months?”
