Once you start talking to the girl, you can flirt with her a bit by asking questions to show that you want to get to know the girl while teasing her at the same time. You don’t need to ask anything too serious and should keep things lighthearted so you have a fun, easy conversation going. You can ask her questions about her hobbies, about what she likes to do for fun, or about her pet cat; just keep things fun and easy and don’t make her feel like she’s being interrogated. Here are some examples of questions you can ask:  “So is blue your favorite color or do you just wear it because it matches your eyes?” “Do you spend your evenings hanging out with your cat or are there other things you like to do for fun?” “Are you really a Giants fan or do you just like wearing orange?” Another way to flirt with the girl is to give her a nice compliment to show that you really do like her. You shouldn’t compliment any parts of her body or say anything too sexual, but you should point out something great about her appearance or her personality to show that you want to get to know her more. Here are some things you can say:  “Has anyone ever told you that you have the most incredible laugh? I’ve never heard anything like it.” “You’re the only girl I know who looks great in neon.” “You’re really good at talking to new people, aren’t you? How do you do that?” You may be too nervous to really pay attention to what the girl is telling you when you first come up to her because you’re so worried about keeping the conversation going. However, if you really want her to like you and to show that you’re interested, then you have to make an effort to really listen to whatever it is she says to you so she sees that you want to do more than just pick her up. Here’s what you should do:  Make eye contact Put away your phone Don’t interrupt her or give her advice when she’s talking Don’t try to compare her experiences to yours when she’s trying to say something serious Bring up something she mentioned earlier in the conversation later on...

TL;DR in Indonesian:
Lontarkan beberapa pertanyaan. Puji dirinya. Pastikan Anda benar-benar mendengarkannya. Tanyakan bagaimana harinya sejauh ini. Goda dia sedikit. Coba untuk tidak mendominasi percakapan.
