I thinnk I'm crazy baby, let you off the hook too easy

Boys. They're so infuriating. I can't even describe how unbelievably frustrated I am right now at the fact that I can't get through to them, ANY OF THEM. You think you know how to turn on the charm. You can be sweet. You can be mysterious. You can even be frisky. But any which way you put it, 99% of the time you will be wrong. And now you just look like an idiot who seems desperate and annoying. So please, if anyone has any advice on how to get someone to flirt back, enlighten me.
