Two Kindergartners Discuss Vomit

     As I was washing my hands in the school bathroom the other day, I overheard this conversation between the two kindergarteners in the nearby stalls.  This was a co-ed bathroom for the kids.  I've changed the names to protect the innocent.

Adam: Sofie, are you there?

Sofie: Yes.

Adam: Do you know that some people drink vomit?

Sofie: Ack!  Really?

Adam: Yes.

Sofie: Do you?

Adam: No.  Well, I have.

Sofie:  Really?  Was it bad?

Adam:  Not as bad as drinking blood.

Sofie: Yeah, my blood doesn't taste very good.

Adam: Yeah.

     So this is a real conversation that trumps just about every fictional conversation I've ever read for a great opening, surprise twists and a universally accessible subject matter.  Can you capture the these qualities in a fictional conversation and not have it sound stilted or artificial?  That, I figure, is one of the great quests of the writer.
