Express doubt and persuade

UNIT 9

Núria: Hey, Marta, what on earth is that?
Marta: Oh, I got it this morning. What do you think? Do you like it?
Núria: Mmm. I'm not convinced.
Marta: Don't you think it's interesting?
Núria: Er, sort of, but I'm not sure about the face - it's a bit mad. 
Marta: Oh, come on! It isn't that bad. It's really colourful. It's good to have a new picture, anyway.
Núria: I suppose so.
Marta: Don't worry, it'll be fine. It'll grow on you.
Núria: OK. We'll see.
