Thanks guys. I believe Hobbit and Sebo are correct in their anlasys and my reaction to the situation could have been a lot better.
A better way would have been to arrive, make friends with everyone, and then to have greeted and thanked her (when things started getting too busy and distracting) and suggested that we meet for coffee later. Much more mature and attractive then getting unbalanced and emotional.
At that time I believe I was (and this is a personal sticking point) too stuck in my own head trying to remember the steps and not in a fun, friendly state.
I have since learned that I should stop trying to take the game so seriously and just let the interaction flow normally. I believe that, at that point, I had confidence and self worth issues that needed sorting out. Once again my brain got in the way
After some real reflection I have concluded that I ALWAYS perform much better and more naturally when I let my game flow from my subconcious and make small corrections after. I think it is important to point out to all the newbies out there that being in a friendly, relaxed and non insecure mood will make your game 500% better as opposed to over studying/thinking and preparing.
I will update you guys with the situation after I call her to apologise. Even if that is all I do. This action should have positive effects on my self image and it is the right thing to do.
