how would you guys respond to "where have you been all my life?"

off enjoying life to the fullest, but i think our energies have drawn us together for a reason.

conveys you love to live and have fun, are enthusiastic and adventurous, at a higher energy level than her. Important to mention that your energies have brought you together. Also if you can come up with some c+f reply that would work too, but make sure to convey specific high value male characteristics.

i would say, as a still transforming AFC, that an AFC answer would be:
her: where have you been all my life?
you: waiting for you

sounds like something cool some smooth guy would say in a movie, doubtful it would work infield with HB 8s and above. "What a loser, youve just been waiting for me, dont you have a life?" haha.

I thought that would make a cheesy fun line for a guy to use as an opener.

Go up to her, best if she's just standing somewhere, go eye contact, and whisper "where have you been all my life?"

Don't know how you can do that without appearing overtly creepy though, you'll prob get silence, then go do the bumbling englishman thing, "oh, i've gotten ahead of myself, my name is ___" then act like you never used the line at all. Kinda like the apocalypse opener.

someone field test this?

First thing that came to my mind was:

HER "where have you been all my life?"

YOU "trying to avoid you, but tonight I just got lazy"

Where have you been all my life?

"Whoa, no, no, no! Thats not what you are supposed to say! You are supposed to say, hmmpf, Im not THAT kind of girl!"

"You tell me, I have no idea."

"I thought I was enjoying life but clearly there was a new level of entertainment, talking to you."

"Outside your bedroom window but now its no fun anymore."

"All your life, ah you mean the last 15 years."

That would be a very odd thing to say for a girl.

If a girl did say that, however, I'd know from my social calibration that I have an opportunity to be as equally "creepy" as her statement "Where have you been all my life?"

My immediate response was "Admiring you from afar, of course "

IMO it's a lot more important to SOI than to neg. Giving a Statement of Intent communicates more assertive masculine energy that will attract the passive feminine. You should only use negs to calibrate SOIs that went a little too far. Yes, I use microcalibration even though people say I teach "natural game," whatever the hell "natural game" means.

And, if a girl says something that would normally be classified as "creepy" because it shows too much interest out of context, you should definitely match her state of interest as soon as you can so that she doesn't feel that unmatched-interest vibe. If a girl feels that interest levels are not similar in an interaction, something is "creepy." If you don't match her own damn creepiness she might end up justifying her feeling of unmatched interest as you being creepy!

Actually Chief you are right... This may be one of the only creepy lines girls use. It is really wierd when girls are too "on".
