" Q. How does flirting work? A. The simplest and least embarrassing way to flirt is just to make eye contact with that special someone. Then hold the look for around two seconds. (That’s an eternity in flirt time!) Going too much longer turns it into a staring contest, which is sort of weird and NOT flirting anymore. While you’re making eye contact, smile. Then look away. That’s flirting! "
