Often times when you're out with your friends in an environment where everyone knows each other, you may find it extremely difficult to strike up conversations with girls that you already know.
What do you say?
Hey, Chem class was great today!
So, you come here often?
That's a cool scarf, where'd you get it?
It's tough. Even after I was able to do cold approaching, this was still a problem for me from time to time.
Here's what I've discovered works.
Start with "Hi!" and a smile. Immediately KINO. Touch her arm, back, anything.
Make a statement. I've found that in social circle pickup, you have to start with a broad statement, it's a subtle way of controlling the frame and taking lead. Questions just sound weird. So make a broad general statement about the bar "you know, I just love this place"
She will then ask you "why?"
Ball is in your court.
"I really just have a great time every time I come out here. I think it's the intimacy. Like, last weekend at that frat party, I couldn't really connect with anyone because there was too much going on."
SHE WILL AGREE WITH YOU. She will be like, "yeah..i know what you're saying..."
Don't take over the conversation here, there is a "vacuum" (credit to Juggler for this concept) of silence that she will then fill. She will fill it by relating to you and talking about an experience etc.
Then from their just vibe off of what she's saying. So if she's talking about this party over on such and such street, maybe you ask her what she thinks of that street, because you're thinking of moving there. Maybe she tells you about a fraternity party....ask her how she feels about them, or fraternities in general.
Now you two will be on the same page, vibing and having a good time.
Take her to grab a drink. Buy her a beer. OH NO I SAID IT! Share a drink together. Hang out. Bring her into your circle of friends Have fun. Escalate the Kino. You're in.
If you already know people then it's far easier to start a conversation. Just say "Hello". You'll already know enough about them to chat to them for awhile, and if it's a group the conversation will certainly just roll.
