I need advice please. I went for an overnight party. I'm still there as I'm typing this. There were 2 girls dancing close to me. It looked like one of them was into me cuz our eyes kept making contact. I was too chicken to do anything cuz I kept thinking of what to say after going over to say "Hi". Honestly what kind of conversation can I have in a party with an attractive girl, what would I say? Should I ask her where she's from or how she's enjoying the party?

Here's the kicker, her friend got approached by another guy, I was super impressed with the guy cuz they were talking for a while and I was wondering what the hell were they talking about. So the girl I'm attracted to looked like she was disappointed that no guy came to talk to her while her friend got approached.

So there's that. How can I strike up conversations in a party with music playing in the background. And what should we talk about?

PS: her and her friend are already gone.
