Here's something I've never done before. I'm quoting Hitch.
Quote:
Basic Principles - no woman wakes up saying "God, I hope I don't get swept off my feet today!"* Now, she might say "This is a really bad time for me," or something like "I just need some space," or my personal favorite "I'm really into my career right now." You believe that? Neither does she. You know why? 'Cause she's lying to you, that's why. You understand me? Lying! It's not a bad time for her. She doesn't need any space. And she may be into her career, but what she's really saying is "Uh, get away from me now", or possibly "Try harder, stupid"**, but which one is it? 60% of all human communication is nonverbal, body language; 30% is your tone, so that means 90% of what you're saying ain't coming out of your mouth. Of course she's going to lie to you! She's a nice person. She doesn't want to hurt your feelings. What else she going to say? She doesn't even know you... yet. Luckily, the fact is that just like the rest of us, even a beautiful woman doesn't know what she wants until she sees it.
* - Ding. She might not leave the house or go to the grocery store with meeting you in mind, but that doesn't mean she isn't open to the idea.
** - This is his way of explaining shit tests. Either she wants you to go away or she wants you to try harder... so keep trying and you'll find out which. It either pays off or it doesn't, and if it doesn't, whose loss is it really?
As for how to approach, do what you feel is right for you. Do what suits your personality. Be real with her. You don't need a specific technique for a specific place... you just need to be real. So what if she knows you're hitting on her? It's no secret that men want to be with women and vice versa; to deny this is lunacy.
