Ha ha, that approach looks more succesful than it turns out to be. You’d be surprised (well maybe not) at how many girls will give you their number and flirt with you, only to do an about face once you start pursuing things further. I tried this once; chatted and got a girl to give me her number and email while she was working at a till, and walked outta there thinking I was hot sh*t.
Tried calling, emailed, and finally a couple weeks later she replied saying she’d been avoiding me because she wasn’t interested… but you’d never have known it by how she was acting when I was there in person.
So if you have no personality to go along with your balls of steel (NO!! I’m not saying I had no personality :D), you’ll just end up rolling them around in your hands after all your sure-dates cancel while your buddies think you’re a God… so it’s good for your image, but doesn’t do much for reality.
