I think that's the biggest things several people keep missing. It isn't that flirting is forbidden. Flirting should be worked up to, and should be stopped immediately if the other person isn't interested.

Just like racing, if you try to gun it right off the line you're most likely just gonna lose traction and smoke your tires out. You gotta ease onto the throttle and ease off it if you start losing control.

I don't like racing so no idea why I chose that analogy.
