I'm not a fan. In fact, I really don't like Brad much but I have to admit a certain sense of empathy, in fact, I actually identify with the Brat (whoops) I mean Brad. It's the way he tries to get really close to his girlfriends, to get inside their skin. To be them and he does it very well.
OK, so he's an actor and actors imitate other people but you have to admit that Brad's talent is really special. I'll confess to doing the same thing in my younger, evil youth. It is the most effective seduction tool known to man (or woman). Just "mirror" the person you want and 9 out of 10, you're home! "Gotcha"!
Is it just flattery? Imitation being the most sincere form of flattery?
No, it's something much more. It's a way of showing someone that you really approve of them and the way they look, dress or act. It always produces a very warm, fuzzy feeling of security that just naturally opens the door to intimacy. (sexual and otherwise)
So the next time you're having trouble with your partner, get a pair of sunglasses just like her's and change your hairstyle.
