Hey all, there's this girl in my class and she's really cute. Guys are constantly talking to her, I haven't yet. The following happened though.

Thermodynamica class was done, I stood up and so did she, then I looked her in the eyes for 3 seconds and she was looking back all the time. I then said hi. That was it. I also made a joke in a lesson today and the whole class was laughing, her as well.

How should I play this? Should I wait a bit while all the other guys desperately try to get her attention? Maybe try an ESP routine?

Advice would be appreciated.

Hey mate. Don't use a canned routine just be yourself. It sounds like you're doing it right playing it cool, and not giving her too much value don't put her on a pedastial like the other guys are doing. What I would do is if you don't have an opportunity to talk I class I'd try my best to make solid eye contact try and get a smile then casually approach her after class and ask her if you can carry her books for her... Just kidding DON'T do that lol. Just have a casual convo and depending on how you feel from there ask her if she wants to get a coffee. Aside from that just be yourself, be confident, but don't rely on pua techniques to attract her because that's not you and she'll see through it. Anyway good luck.
