Do your arguments with your girlfriend usually end up with her admitting that you're right and that you know better than her? And you actually believe her? Even if she realizes she's wrong, chances are slim to none that she'll actually admit it. The fact is that many women will tell you that you're right to shut you up, but what they're really thinking is: "He'll find out soon enough that I'm right." Then they'll proceed to find some devious way to prove their point to you.
