I have been a sedditor for quite a while, I have banged chicks and I know all about Kino, closes and everything but when I am not drunk and don't go straight to the Kino phase what the hell do I do?

I went skating with a friend and he brought two attractive girls, one of them kept flirting with me and I did some kino but besides that I had no idea how to flirt on a social level, what do I do?

I feel I missed the opportunity because I didn't know how to casually flirt and could really use some advice.
