I just made that opener up then.. LOL, just be creative guys!
Okay so a double sided compliment would still be indefinatly a compliment but your saying to her.. I approve.. but i know you could do better!
As an example, your talking to some brunette.. As before we'll use "hey, your hot" but then add somthing like "but have you ever thought about going blonde? It would really bring out your eyes, it would make you look much more attractive."
Or if she has pale skin you can tell her she would look stunning.. but only if she wore red because it would make the sexiest contrast with her fair skin.
A double sided compliment lets her know although she is hot.. There's still room to improve! Every girl wants to feel sexy this is why they dress up! THEY DO IT FOR YOU.. TO APPROVE.. OF THEM!
And when you stand out from the rest of the guys who just kiss her ass and you use a double sided compliment instead, trust me if she likes you.. Yes guys, she will go out of her way to go blonde just for you.. or wear red or whatever! Why? Because if you matter to her.. Then she will do ANYTHING to get your approval, simple!
By doing this you look confident and it shows that you know what you want in a girl and your not afraid to say it.. your a guy who doesn't just settle for anything. Not many guys have the balls to tell a girl what she could do better to improve herself!
But remeber guys.. You need not worry so much about openers, what's 100 times more important is the follow up question you have that makes her invest in conversation!
