Quim - Hey, Pau, look at this.
Pau - What?
Quim - This necklace. What do you think of it?
Pau - Not much, why?
Quim - Don't you like it? I think it's really cool.
Pau - Well, it's OK. I suppose. But what about this underpants? It's very beautiful.
Quim - No, I don't think much of that. I can't stand that colour.
Pau - Oh, well we can't all have good taste.
