Sergio is talking with his girlfriend,

　　Tyra: Sergio, we have to talk.

　　Sergio: About what?

　　Tyra: About us.

　　Sergio: There is nothing wrong with us. We are doing fine.

　　Tyra: Let's be serious. We've been dating for six months now and I really like you...

　　Sergio: But...?

　　Tyra: But you're not dedicated to this relationship. You see it as casual dating.

　　Sergio: How should I see it?

　　Tyra: I don't want to be like this. I think we should take the next step.

　　Sergio: Is it time already? It has only been six months. Our relationship hasn't had a chance to mature yet. There are still some hurdles we have to jump over.

　　Tyra: Like what?

　　Sergio: Like last week I saw you letting Brian kiss you.

　　Tyra: It was only on the cheek.

　　Sergio: So that is okay then? It starts on the cheek and pretty soon you're French kissing in the back of his car.

　　Tyra: Don't be ridiculous!

　　Sergio: So it is okay then that I kiss other women on the cheek?Tyra: Definitely not!

　　Sergio: You see. We still have a hurdle.
