Well then just be yourself .. I know.its so freaky when your hearts pounding and the significance is greater than you ever would.want to lead on. Honestly, just smile. Keep smiling, maintain eye contact. Be interested in listening more than sharing. That's all I got
TELL HER ABOUT IT AND ABOUT HOW JUST BEING NEAR HER MAKES YOU FEEL!! She will most likely be flattered! Then just talk to her as if you have been friends for YEARS!! lol Good Luck!
Strike up a short conversation that is centered around something you two have in common. That's one way to start.
Do any of your friends know her? Or do you know any of her friends?
ha....it'll pass - just don't let the oportunities do so....
