Mind, flirting with someone you do know is already scary enough because of the ever popular concept, the "friendzone."  There generally seems among women to be this aversion to dating male friends?  Gotta hook up with complete strangers I guess, except men approaching women seems to be becoming taboo, and women at large aren't taught to make any advances.  Except maybe on tinder, which is basically a buffet table for women and the few men that won the genetic lottery (supposedly studies show this.)
