Hey guys, completely new to PUA stuff. I read a lot about it, but haven't put much to the test. Anyways, met this girl from class (we're in college), got her number (going by M3, I only got to A2 during the first convo with her and her friend...) Texted her Monday (and as you will see, it's super dragged out):

Me [01:52]: Whoa HB, I just saw someone that looked exactly like you! There's a little problem though..
HB [03:18]: Haha what's the problem?
Me [03:47]: She was wearing this velvety fuzzy Santa hat, which looked cute, but you wouldn't believe what's written on it!
HB [05:59]: I've never seen a santa hat with stuff written on it
Me [08:41]: It read "Naughtiest [heart]" in pink on the white rim of the hat. I couldn't believe it was you because she also had these really obnoxious knee-high boots on, strutting down the street. Any side jobs you want to tell me about? ;p
HB [09:07]: Come to think of it...that's exactly what I was doing today, its not like there are exams or anything
Me [09:33]: Oh ya I did study a little after I came back from my jog as well. Love running in this weather, you're body gets all hot on the inside but the air keeps your skin cool and tingly. Anyways, gotta attend this event at dorm. Catch ya later!

Exchange 1: (so far so good)
Exchange 2: (She sounded more annoyed/distant. I know she has an exam the next morning, so I had a dilemma; either I continue with it, or I continue it the next day, which would've dragged it out for even longer and made the punchline a colder text than it already is)
Exchange 3: (Now, if she didn't add the sarcasm at the end about exams, I would've continued the thread and it would've made a good callback for later. But the last part of her message sounded like she was completely annoyed so I stacked and stopped)

I made up this routine based on one of Vin Dicarlo's examples in his books.
The purpose was to:
Create conversation from a weak first-meet
Create sexual tension (with intrigue at first, then charged vocab at the end)
Create a good callback

So yea, I'd say it didn't go even close the way I wanted it to.
What were some things that I could've done differently to produce a better result with this routine?
Was it just because her exam frame overpowered my text's frame?
Or is it just a bad routine in general?
Should I take out the middle text? I feel that she got annoyed by me trying to create too much intrigue (but at the same time, dragged it out), and lost her interest.
