Please help, how do I ? ill answer your question if you answer mine.?

Okay so there's this really popular girl that wants to hangout with me. I don't know even why, I'm no where as pretty as her, I'm not rich & I'm definitely not cool. When we hang out, I have no idea what to talk about, so how do I start up the conversation? I don't want to play would you rather or any of those stupid games. Please help, I'll choose a winner for 10 points. I need idea's & I'll answer your questions
