The following dialog is for questions 14 to 17.

Farah: Hello, Arsyad. Where are you?

Arsyad: Hi, Farah. I'm so sorry, I forgot to tell you. My mom asked me to accompany her to my uncle's house. I'm on my way home.

Farah: We have waited for you for an hour.

Arsyad: I'll be going in 15 minutes. Will you be waiting for me?

Della: Take your time. We will be here waiting for you. Besides, the movie will start at 7 PM.

Arsyad: Alright. Wish I can get there in time.

Farah: We're so sorry that we have our meals first. But don't worry, we're going to have snacks after watching the movie.

Della: By the way, would you like to have popcorns? What is the flavor? The sweet or salty one?

Arsyad: Hmm. I prefer the salty one. Thank you. What about the others?

Farah: We'd like to have sweet popcorns and iced tea.

Arsyad: I'd love to have one too, with no sugar, please.

Farah: O.K., call me on your way upstairs, in case you are late. I'll come to you.

Arsyad: Thanks. See you there.

Farah: See you.
