Most of the time I guess you want to be in flirt mode with a girl you're interested in right? And preferably turn it off when talking to your buddy's girl etc.

So I was in a computer lab today, saw a girl I just met recently, IMed her from a few rows back

"Hey I'm at the lab now, there's a girl who looks just like you from behind"

pretty witty if I might add

So I asked her to turn around, she sees me and then WALKS OVER TO ME.

I was like 'holy shit!' that has never happened b4 (I'm a newbie)

Problem is I don't know how to flirt, I remain seated while she comes over and we talk about work(boring I know). I ask her what music she was listening to and get a "I dunno". I get lost here, didn't know how to transition or whatever I'm supposed to do and she went back to studying.

So Sticking points
1) Dunno how to flirt
2) I make boring conversations (work, school, job) and I don't know how to introduce interesting topics.

Use somtimes:
"Oh that reminds me..."
It doesnt matter what you say, at least try to make it positive/interesting.
It can be a story, a random fact or an article from a newspaper.

But dont overthink it!

HA! in college, when i get stuck, i like to use my chewing gum technique. Which consists of:
me:"hey *getting out gum of pocket* you want one?"
her: "yeah, sure"
me: "k *starting to give it to her* wait! you have to win it first!"
her: (interested) "how?"
me: "THUMB WARS!!"

then you juste play with her. u can cheat, its funny and she gets more talkative cuz you got somthing to talk after that, and its good for kino, and comfort

(this is all field tested, works like a charm)
