Мне надо сделать диалог на тему подарок другу

-привет!у тебя завтро денюха? -как помню да. - а что тебе подорить? - незнаю.

- Hello Sam. - Hello Mark. - How are you?-  I am fine, thank you. And you? - I am fine too, thanks. Do you know that tomorrow is Linda's birthday.- Oh! Of course, I forgot it. What will we give for her? - I don't know too. Let's think: what does she love? - Mmm ... Oh! I remember! She showed me her collection of coins. There are a lot of them in it!- Maybe we will give new coins for her collection!? - Oh! Yeah! It's a good idea. - OK. Let's go. We haven't got a lot of time! Shops will close in 20 minutes! - Hurry!
