Kate: Hi, Leo. What are you looking for here?

Leo: Oh, Kate. Hi. I need a present for my nephew. Some colourful children’s book he can read himself. He’s only four and a half, but he’s learning to read already.

Kate: Clever boy! But I think at his age, it’s healthier to spend more time playing in a park, in a playground, not sitting over books.

Leo: Oh, don’t worry. He plays a lot. And you? Looking for a textbook?

Kate: Yeah, I need a reference book for our maths classes. I’ve chosen this one. What do you think?

Leo: It will do. Yes, you can find everything here. Lots of tables…and it’s presented very clearly. It’s worth buying.

Kate: Maths has always been a problem for me, and I also want to buy something to read on biology.

Leo: To read on biology? What do you mean? Some thriller about cactuses, or a love story about a beautiful white mouse?

Kate: Biology is not only about cactuses and mice. It’s a very interesting subject, and I read much more about it then we need to do for homework. I would like to work as a biologist or as an environmentalist in the future.

Leo: It’s an interesting job, I believe. And it usually means lots of travelling. You’ll see different places with different animals and plants. But it also means you have to go to university.

Kate: Probably. But one day I will. But not right after school. And I don’t have any travel plans for the near future either.

Leo: Do you want to find some work first? To gain some work experience?

Kate: Yes, it’s my plan. I think young people need to work a bit. To understand what they like, and what they want. And only after that to make decisions about university and serious careers.

Leo: It’s reasonable. There’s an old Chinese saying that “It’s better to stand and wait, rather than run in the wrong direction.”

Kate: Clever! Did you know that they’ve introduced a new course on Chinese language at school? An optional one. Would you like to try learning it?

Leo: No. French is my limit.

Kate: Yes, I also learn French…and German too. I like French more. German sounds too harsh to me.

Leo: Probably. In my school, only French is obligatory. And we can take one more foreign language if we want – Spanish, Italian, Russian. I took none of them.

Kate: You are just lazy.

Leo: No, I’m not. I just don’t have a gift for language, and I know it.

Kate: But you are very good at sports, aren’t you? You take part in all the school competitions, in all possible kinds of sports.

Leo: It’s because I love it. My training program is designed for seven days a week.

Kate: Don’t you relax even on Saturdays and Sundays?

Leo: No. If you really want to achieve something in sports, you need to do it every day.

Kate: Wow! And you cycle to school and back every weekday too, don’t you?

Leo: Yes, I do. In any weather. It’s great training, and I’m never late.

Kate: I should probably try it too. I usually go by school bus, or my mum drives me. Going by bicycle sounds really extreme to me.

Leo: Oh, just try, and you’ll get used to it very quickly.
