I never have anything to talk about.

[Cronus]

Make small talk. Ask the others about themselves, and ask question about their statements.

What not to do?

• Don't ask too many questions, and especially not personal questions.
  
• Don't be pushy. If you see that someone is feel bad, and wants time alone, don't force them to tell you what's wrong.
  
• Think before you speak - Don't ask awkward questions.
  

If someone doesn't show interest in you, don't take it personally. If I'm having a hard time communicating with someone, I add them on Facebook or text them, to get to know them better. Then, I feel more comfortable talking to them in person.
