How about talking about Music, what musical interests you have in comon or different with others. Music is usually emotional and passionate for most, and a real good conversation starter!
How about talking about school, what you are doing, how much it SUCKS...lol
You could takl about where you are from, and ask where they are from. Discuss your little part of the world!
What are your hobbies or interests? You can talk about that, or what you really HATE to do...
OK, those are my suggestions, I hope it helps!
Love, Dara
