Alex: Hello. My name is Alex.

Rosy: I am glad to meet you, Alex.

Alex: And what is your name?

Rosy: My name is Rosalinda. But my friends call me Rosy for short.

Alex: It's nice to meet you, Rosy. How old are you?

Rosy: I am 19 years old. Where do you come from, Alex?

Alex: I am from Poland.

Rosy: What is the capital of your country?

Alex: The capital of Poland is Warsaw.

Rosy: Do you live in Warsaw?

Alex: No, I don't. I live in a small town in the South of Poland. And where are you from, Rosy?

Rosy: I am from the Russian Federation. The capital of Russia is Moscow. Have you ever been there?

Alex: No, I haven't been to Moscow.

Rosy: It's a pity. Do you speak Russian?

Alex: Yes, I speak Russian a little bit. But I prefer to speak English as I know it much better than Russian.

Rosy: That sounds great! Will you come to visit me next year?

Alex: If you want, I will come.

Rosy: Yeah, I'd really enjoy it. What is your favourite musical band?

Alex: I like to listen to different types of music beginning with heavy metal and ending with jazz or country.

Rosy: Do your friends listen to the same music?

Alex: Unfortunately, they don't. They like rap. Sometimes they say to me, "Turn off that awful music!".

Rosy: Is it offensive?

Alex: Frankly speaking, no. I love my friends. We are fond of spending our free time together.

Rosy: How often do you go to cafes or restaurants with your friends?

Alex: Not very often. We prefer going for a walk to sitting at the cafe.

Rosy: Cool. And Alex, do you have a girlfriend?

Alex: Oh, I think, I really like one girl but I don't know if she likes me too.

Rosy: Why don't you just ask her about her attitude?

Alex: I'm afraid of her answer.

Rosy: Oh, it's clear. But I wish you good luck.

Alex: Thank you, Rosy. And do you have a boyfriend?

Rosy: Yeah, I do. He is a little bit older than I am and much wiser.

Alex: How does he look like?

Rosy: He is very handsome. He has hazel eyes, brown hair and a soft voice. His hands are warm and caring.

Alex: Did he say that he loves you?

Rosy: Yes, he says it every day. I'm happy with him.

Alex: I'm happy to hear it. You are a good girl.

Rosy: Alex, can you describe your appearance?

Alex: Of course, I can. I have big green eyes, fair hair and a brawny figure.

Rosy: Do you go in for sports?

Alex: Yes. I'm good at football and volleyball, and my hobby is tennis.

Rosy: Wow! It's great!

Alex: Thank you. Do you play any musical instruments?

Rosy: Yes, I do. I play the piano and I'm learning how to play the guitar now.

Alex: Is it difficult?

Rosy: I think no. But I really have passion for music. Maybe that's why it is very easy for me.

Alex: Alright, I understand.

Rosy: Alex, sorry, but I have to go. My parents call me to have supper.

Alex: When will you return?

Rosy: I think tomorrow I will be here.

Alex: I will wait for you.

Rosy: It was a pleasure to talk with you, Alex. I feel that we may become good friends.

Alex: I hope so. Please, come tomorrow.

Rosy: Let's organize a singing contest here.

Alex: Ok, I will be ready with my best song for you. Goodbye, Rosy.

Rosy: Bye, Alex. Don't miss me too much.
