Okay guys, so I made my first two approaches today. They were relatively successful. No slaps, no screaming, no humiliation.

Girl #1:HB7.5
She was walking a bit ahead of me. I was walking with my buddy (who didn't know what I was about to do). I used the "jealous girlfriend" opener, and she gave a response. We kept walking the same way (my destination wasn't set). We fluffed a little bit, I made some sarcastic remarks. No negs though. Then I "closed" with: "well, how about I get your number in case I have more lame opinion questions to ask you." She laughed on cue and said "sure". I got her number.
I texted her a bit later, and she asked me to meet her somewhere. She was with her friend. We just fluffed some more, and I had to get to class, so nothing happened.
So, guys: I got the opener and I got the number. But no chemistry, and no attraction. I did no DHV stories or anything like that. I basically just did cocky funny, but I got no IOIs. So what should I have done with her to get that attraction? We were both walking, so what kind of routines could I do then?

Girl #2: HB9
Same opener. Walking around the school. Got a similar response. Similar fluff. Similar close. So what could I do to get her attraction towards me?

Thanks guys. Really appreciate it!
