So tonight I am going to a club. Which has hard house and EDM music to dance to. Ofcourse, like the gentleman I am I want to talk to girls and have a fun night. But I've gone to several clubs now, but I seem to lack the ability to have a good conversation with girls I do not know.
This is how it goes so far, after I notice a girl is into me (she's dancing and looking me in the eye etc...):
> Hi, having a good night?
> Yeah! You?
> Me too! What's your name?
> Melissa.
> Cool, where do you come from? OR Cool, that reminds me of a friend of mine who is....
> Anontown OR Cool
What do I have to chat after this, or do i need to do it in an other approach?
All advice appreciated
P.S. I'm looking like a 5/10 or 6/10 by harsh judgers.
