The surest way to scare off an obviously learned and self-possessed man, who is vaguely interested in you, is by
1) dissolving into slightly hysterical and extremely screechy giggles that are more befitting a teenage chimpanzee than a grown ass woman;
2) blushing so furiously as you giggle that that you feel lightheaded and flush and are reduced to futilely fanning your tomato-colored face with your hand and, ultimately, left with a pounding headache; and, finally,
3) admitting to the man that you’re blushing, hysterical and lightheaded because you’re nervous as hell that you’ve revealed all of your neuroses to him in the first shot.
You might want to start by practicing restraint and speaking at a pitch that is below the threshold of pain and discomfort.
Super! Good luck in the future!
ps: You're a dork. Thanks!
