Здравствуйте, пожалуйста помогите переписать вот этот диалог в косвенную речь.
Lucy: Oh, no, I can't believe it! What am I going to do now?
Jane:
Lucy, what's the matter?
Lucy: I've just killed a poor little spider - look!
Jane: Oh, dear! Try not to worry too much. It was an accident, after all.
Lucy: That's not the point!
Jane: What do you mean?
Lucy: Well, killing a spider is bad luck! Didn't you know that?
Jane: Oh, no! Now you'll never pass your exams or win that school writing competition you entered!
Lucy: It's not funny, Jane! I'm really worried about it.
Jane: I'm sorry. I don't mean to make fun of you, but REALLY, Jane! Killing a spider is bad luck? You don't really believe that, do you?
Lucy: Yes, I'm quite superstitious, you know. I never go anywhere without my lucky charm.
Jane: Well, I think superstitions are all a load of rubbish. I walk under ladders all the time and nothing bad ever happens ... hey, is that your mobile phone ringing?
Lucy: Oh, yeah ... oh, it's Mrs Smith, the English teacher! Maybe I did win the competition!
Jane: You see! Forget the spider! Quick, answer it. Perhaps it's your lucky day, after all!
