1. Just be yourself. I know that's cheesy, but it's true.
    Say hi, ask them about themselves, find common ground.

  2. Be honest with them. Be upfront with your desire to get to know them but you're a bit nervous/unsure/anxious (whatever it is)
    If they don't react well to that, you probably don't want to get to know them in the end.

  3. Pretend to pass out so they can give you mouth-to-mouth

  4. Just say "Hi, I don't think we've met. My name is..." all let the conversation flow. But be prepared with at least one topic
