Diana attends a Japanese club at school. She meets Angga from another class for the first time.

Diana: Excuse me. What time is it now?

Angga: It's twenty past two. The club will start in ten minutes.

Diana: Thank you. Anyway, I am Diana from Class X Language 1. What's your name?

Angga: I am Angga from Class X Science 2. Nice to meet you, Diana.

Diana: Nice to meet you too, Angga. By the way, do you know Sylvia?

Angga: I do. She's my classmate. Do you know her too?

Diana: I do. She's my neighbor.

Angga: So, you live in Graha Sejahtera Residence, don't you?

Diana: I do. I live next to hers. Have you ever been to her house?

Angga: I haven't, but I know that Silvia and her family live there.

Diana: By the way, you are from a science class. Why are you interested in joining this club?

Angga: Well, actually I love science and language, especially Japanese. By mastering foreign languages, communication will be fluent, right?

Diana: You're right. One thing I do to master Japanese is by reading manga. What about you? Do you like reading Japanese manga too?

Angga: I do. I have several at home, but I still need to improve my Japanese skills.

Diana: Don't worry. Everything is a process. Anyway, do you want to have a trip to Japan?

Angga: That's my dream. I do hope I can visit beautiful places in Japan. Besides, I'm interested in learning about Japanese cultures and positive attitudes. You know, they are acknowledged for their discipline.

Diana: They are. Anyway, do you have Japanese e-friends?

Angga: I have one and we often communicate via social media.

Diana: That's great! By chatting with the Japanese, you will be able to speak and write Japanese more fluently.

Angga: I hope so.
