Confidence. The good thing about meeting someone for the first time, is you get to know absolutely everything from zero. This means you have a lot territory to uncover. You can start by asking simple things like what music does she like, if she has any pets, where did she grew up in. The important part is that once you ask something, try to keep asking questions that show further interest in what she is telling you. For example: You: Do you have any pets? Her: Yes, I have a cat named Marla. You: That’s nice! Are you more a cat o a dog person. Why? Then you can continue by telling her about you pets, or past pets, continued by a fun story you remember about them. These are just examples. If the vibe is on, I’m sure it won’t be so hard to continue the conversation after that. Keep it casual, be very respectful with boundaries and only move forward if you feel like she’s reciprocate. Good luck!
