He did pretty good. He was laid back, wasn't going crazy for her, didn't try too hard, didn't bombard her with questions, was relaxed, easy-going, and light-hearted, made her laugh, and let her chase him. He played it cool, and she loved it.
What do you think game is, exactly? Being fake, acting like a douche bag, charming her pants off, being ****y and sarcastic, busting her chops, talking about shallow topics, bragging about status, acting like a social clown, looking and acting like a bad boy / player? He was just being himself. Imagine that.
I think there's a lot of over-exaggeration on what is required to attract women - based on stereotypes and personal failure. It's not that complicated - only in your head. I do this kind of **** all the time, and it works great. You don't need any special skills, or be some badass extravagant super exciting alpha king pin. Just be a decent, cool, laid back, interesting guy. Looks matter a lot, of course.
Stop listening to DeAngelo, PUA's & co. They don't know anything. They're living in a fantasy world - right across from the nice guys. The blue pill is in the middle. Reality is very simple and easy. Just as he just showed.
A lot of guys make attracting women out to be bigger than it is. Likely because they're not successful, and make too many assumptions. They're still pedestalizing them.
