Мне надо сделать диалог на тему подарок другу

- 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!
