Stage fright! wow!

           ok so ive known about the game for awhile now which means ive heard over and over again about the three second rule to cure approach anxiety. even with that and jdogs journey thing to help get over it i had a total stage fright that happened at a party i was at. lets take a little trip down memory lane shall we?
            alright so im at a chick friend of mine's bday party and its pretty chill. its night time, its outside, they have music playing and a beer pong table set up all in her backyard. well about half way through the night im standing with my friend and another girl that i just met and i glance over to the beer pong table. i see this guy playing against this girl and the girl is probably the best looking girl ive seen all night! i was blown away! i hadnt even seen her there till that moment and couldnt believe i missed her. anyway she was playing against this one guy and had two other guys standing watching. i new about half the people at the party but that little group was some of the people i didnt know.
            ok now im a social drinker but the only problem is that im on this drug that is tough on my liver so my doc told me i cant drink. this is where my stage fright came in. shes playing a drinking game with three other guys, i cant drink so the best i could do would be to stand and watch which would lower my value. so what do i do? when i asked my friend about her he said i should go talk to her but as we all no thats a very vague thing to say. i needed something but i couldnt think of anything at the moment.
          what ended up happening is that i ignored her and forgot about talking to her and just stuck to my friends talking about the rest of the summer. i know epic failure. but thats why im leaving it up to yall. what should i have done? what would have been the best coarse of action? i guess i could have tried opening them all with some type of opinion opener but i dont know. ill leave this one to you guys.
