I have trouble with this and it's one of my biggest sticky points in Game. I can pretty much talk to any girl but when it comes to number closing I suck ass like the Jack in The Box guy. I can lead interactions well now and can get people laughing at my jokes. It's all about the emotions. If you can make a woman laugh then you're one you're way to greatness my friend. I started applying this new method where I open with a funny joke every time I talk to someone. It doesn't matter who. If you can get someone laughing within the first few minutes then the rest of the interaction is going to be good. Get her number after you deliver a punch line. Wanna 'exchange' number/snapchat?
