I never understood why this thing is always going on, that either the girl has to hand out her number or you should.
There's got to be some interest in both of you, so you can actually EXCHANGE numbers to keep in touch.
I keep reading about guys who got a girls number, call them, and they either get rejected by some stupid lame ass excuse or women don't pick up the phone or return the calls. It's because there isn't any interest, she probably just gave you her number to be polite.
I think this is where DD is brainwashing you. Maybe in some occasions if you really "click" with the girl she will hand you her number and return your call regardless of just the "3 minute rule then get her number."
I'm only 16 and do most of my "sarging" at school or night outs (if thats what you wanna call it), so I haven't yet tried to approach a girl at a mall or something, but it doesn't sound right to me that a girl that only talked to you for a minute or two is going to hand out her number, and if she does, return your call and agree to go out with you. Like I said, only if both of you "click."
And the right way to do it is if you both want to keep in touch with each other, EXCHANGE phone numbers. So when you do call her, she will also know who you are and more likely pick up the phone.
