MEN VS WOMEN
You know how when things aren't going well in your friend's life, or day, or whatever? And he or she complains a little about them to you, because you are always willing to lend a sympathetic ear if it gets you out of doing any work? So then, when it's your turn to talk, because you care, you say, "I'm sorry."? You know?
If the other person is a woman, she will respond, "Thanks. Yeah, it sucks." Or some such response, often followed by a continuing litany, but the point is: She recognizes what you meant.
Whereas if the other person is a man, when you say "I'm sorry," he will respond, "It's not your fault."
This is merely an observation. We shall leave the sexist interpretation of this fact, and subsequent flinging of angry rhetoric back and forth, to the commenters of either competing gender.
