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