Be sure and keep the energy SLIGHTLY above hers and really be invested in what she has to say. Definitely throw in the FTC before you start the opener. I'd say start with the Jealous Girlfriend opener, rock away then go back into the "well it's a 2 part question" routine as a complete starter.
I too am only 3 months away from being 21 and getting into the bars/clubs around campus. I'm just waiting for my success to skyrocket after I am able to cover these social watering holes if you will...
In the mean time, just get used to talking to everyone! This will help you calibrate socially (for every interaction, not just pick-ups). You don't have to "open" them but just get the conversational rhythm down so you don't come across as "creepy" or "weird" Trust me, I also used to give off that negative vibe, but then I learned to just bounce it off. Remember whose reality you're in and go with it! I know I'm getting into inner game here but bear with me... One of the attitudes I like to focus on following, is by Pauly Shore's character "Crawl"(see he even has an alias too!) in the movie "The Son in Law" If you haven't seen it, watch it now! He definitely lives by his own rules and has confidence oozing out of his ears!
Keep practicing though man it'll all pay off when that year is up! -Happy Hunting Comrades!
