Гипотеза Парменида гласила, что в мире нет пустоты все состоит из атомов и пустоты

 тут я думаю легче импровизировать...

к примеру:

- Excuse me

- Hello, may i help you

- Yes. Can you show me this present in green box?

- Sure. Here is it.

- How much does it cost

- This present cost 50dollars

- 50 dollars? that is too mach

- Mmm. how about this? it cost 35dollars

- I don't like that one

- A don't know what you want...

- that is nice. How mach is it?

- 30 dollars

- That'll be fine!

- It is all?

- Do you can pack it in good gift box?

- Yes. Have a good Christmas

- Thank you

- Thank you too
