So tonight at a beach party event I met this girl. I opened her by commenting on how many girls have hit on her and yet crashed and burned. She noticed right away I was demonstrating a high social value and she took the bait.
We had a connection and she was giving me ioi's but there was some drama with her friends that kept taking her away so we exchanged numbers. I called hers to make sure it worked and then we parted ways.

So my questions is...
1. When is a good time to call her? How many days later and whats a good time?
2. What do I take her to do? Should i say meet for coffee, drinks, or something more unique?
