<human>: Can you condense the text into a few key points?

I was swimming at this lake spot with 2 of my guy friends and their girlfriends drinking some beers and smoking a blunt, and as we were packing up these 3 girls came by to do the same thing.  I was talking to them as we were packing up, I wouldn't say flirting, but I was learning about where they were from and what their names were and etc.  maybe that's flirting idk, I made them laugh by saying two of them looked like they were twins.  They weren't fyi.  

When we got back to the car I realized I didn't have my phone, so I ran back, asked if they had seen my phone and the one I found the most stunning from the start offered to call my phone.  So I gave her my number to call and nothing was heard since I left it on vibrate.  I walked away and one of the girls found the phone and gave it to me.  I thanked them and looked at the girl i gave my number to and said, call me. And she said okay.

One problem is I don't remember the girls name I liked the most.  I know it started with a C and where she was from, but blank.  I remember the other girls names, but not hers.  What can I do at this point?  Text her, call her later?
<bot>: met girl briefly at lake spot as we were leaving, gave her my number to find my phone, said call me.  What can I do to up my next move?
