If this small talk goes well, share a little information about yourself--just something small like what you do for a living or how you liked the show you just saw, for example. At some point, of course, you'll want to introduce yourself and, hopefully, get her name. The key to sharing information is that you both gradually  open up. Take turns talking, and each time she gives you some information about herself, give similar information about yourself, and maybe give slightly more personal information than she gave.  For example, if you're talking to a girl who says she's taking summer classes, you might disclose that you are also taking summer classes, and then tell her which class you are most excited about. This invites her to disclose more information about herself so that the intimacy of the conversation increases over time. You don't want to share too much about yourself too quickly, and you shouldn't try to get her to do so either. Laugh at her jokes, listen to her stories, and don't get distracted by what's going on around you. It's more important to seem interested than to seem interesting, and you don't want to hog the conversation. Being a good listener is far more important to successful conversation than being witty. Put away your phone (until you ask for her number). This is not the time to check in with your friends -- unless you want her to feel unwanted. If you want the woman to like talking to you, then you have to show that you actually care about her as a person instead of just thinking of her as someone you can pick up. Without getting too personal, you should ask her some questions, either about her life, her ideas, or just about some general topics like her favorite sports team or what she likes to do with her free time. Here are some things you can ask about:  Her family Pets Her favorite movies, books, albums Her friends Her hobbies Her job Show her you think she's a worthy, intelligent being and that you actually care about what she thinks -- beyond whether or not she'll say "yes" if...

TL;DR in Indonesian:
Ungkapkan lebih banyak mengenai diri Anda. Beri dia perhatian penuh. Beri pertanyaan. Minta pendapat dia. Cari persamaan. Buat dia terkesan dengan kedewasaan Anda. Biarkan dia bicara. Menggoda.
