Long story short

I work at a day club I met a girl at work this is not uncommon I've hooked up with a few. Anyways, we hit it off she had to go because he friends were going home. I didn't happen to have my phone on me. So I gave her my number instead. It's been about two days since I haven't heard anything from her. One of my friends happened to have her number and they sent it to me. What should I open with?
