The following dialog is for questions 12 to 15.

Erik: Hi, Diah. Why are you looking sad?

Diah: Hi, Erik. No, I'm just enjoying my last time in this canteen.

Erik: What do you mean? Are you going to move to another school?

Diah: Yeah, not only school but I will move to another country instead.

Erik: Are you kidding me? Where will you go?

Diah: Canada. My father gets a job there, so like it or not, I need to go with him.

Erik: Have you told Sari about it? She may be sad if she knows that you will move out.

Diah: No, I haven't told anybody, except you.

Erik: When are you going to move?

Diah: My father is still processing the documents needed I think we'll be leaving next week.

Erik: Next week? Wow! That is quick. You'd better told Sari about this soon.

Diah: You're right. I will tell her when I meet her.

Erik: Good

Diah said, "No, I haven't told anybody, except you."
