Paradox is
exactly right.
This girl responded the way she was supposed to react. Plus,if you said this within earshot of other people,then how was she supposed to respond?
What was it you were expecting her to do,rip off her clothes and jump on you right then and there?
On the outside,she may he appeared agitated or annoyed,but internally I suspect she probably felt
some attraction towards you.
Don't be surprised if she tries to contact you in some way.
I guarantee you she probably wouldn't have even mentioned you to her friend,or even remembered you if you had did the standard "nice guy" approach.
Now here's the kicker: If this girl indeed does try to get in touch with you,and you start being "nice" to her because you don't want to offend her or make her mad,YOU'LL KILL ANY ATTRACTION she has for you.
The way you were in the beginning is the way you'll have to stay.
IF YOU CHANGE,then her attraction for you
WILL CHANGE as well.
The fact that you asked this question means that you have a slight misunderstanding about how attraction works for women.
You unknowingly found a needle in a haystack. You hit a 90 mile per hour fast ball blindfolded.
The neg worked the way it was supposed to,and you got
worried.
If her tries to contact you,stay the same. Use a
slight neg or two more.
Don't spend the whole conversation negging her,just drop in one every now and then.
If you do meet up with her,tell her you like the shirt she has on,but she might want to run the iron over it a few times before she decides to wear it out again.
You're ok dude,just don't go "nice guy" on her.
