Since Lucas decided on full disclosure, I'll attempt to explain better what I was trying to say.
Lucas, the object isn't to
ignore her.
Think about this... How awful is the "job interview" date? You know what I mean. What do you do? Where do you live? How big is your family? Where did you go to school? etc. It's pretty terrible, right?
Now think about how you've accumulated friends throughout your life. Did you meet them and "interview" them to get to know them better and then you became friends? Of course not! You probably just had a really good time hanging out one time and the friendship formed from there.
Now consider
Social Proof. Social Proof is when people use
other people's opinions to help them form their own opinions. For our immediate purposes this means that if someone sees other people having a good time with you that they'll think you are a fun person to be around.
What you do is go out to have a GREAT time with someone. Just start up random fun lighthearted conversations (avoid politics, religion, etc) with lots of people. When I said talk to everybody in the place
except her it was an over exaggeration. What I mean is don't
focus on her. You're out to have a good time, you're excited to be somewhere fun, and you're going to talk to lots of new people and be Mr. Friendly. Don't
ignore her though, include her in the game.
If you find yourself standing next to someone you could just be like, "Hey man! I gotta tell you, NYC is AWESOME! This is my friend Brooke (put your arm around her like she's your best friend ever), she's been kind enough to show me around town and I'm having the time of my life - hey what's that you're drinking it looks really good! Oh, it's a Budweiser? I couldn't see the label, DUH!" Don't forget to be super cool friendly guy with girls too. You just have to put yourself in the mindset that you're at a party with a whole bunch of really cool friends that you haven't seen a long time, and this is the best night ev4r!
So, what you end up doing is you actually BECOME this really cool guy, you actually
have a really fun time, and you avoid the lame situation of sitting around staring uncomfortably at your drink while you ask each other boring questions because there's all kinds of fun stuff to talk about that's all going on right now. It becomes an experience the two of you share together instead of some awkward stilted conversation.
PLUS, she gets to see everybody thinking you're a cool fun guy too, and that reinforces and validates her perception that you're a really fun guy.
Also, you've just spent the entire night being the total opposite of creepy loner serial killer stalker guy which is a giant plus.
Rember, the point isn't to ignore, the point is to have a lot of fun and to NOT be some creepy clingy asshole people can't wait to get away from.
