Why does Cathy look worried?

M: Hi, Cathy. How are you?
W: Fine, thank you.
M: Are you sure you’re all right? You look a bit worried today. Is there anything wrong?
W: Well, yes, there is something wrong actually. Perhaps you can give me some advice.
M: Of course, if I can.
W: Well, last night when I returned from the theatre, I found that I’d lost my wallet.
M: Oh, dear! That’s terrible! What was in your wallet?
W: Well, some money, of course, my visa, all my identity cards and some photos.
M: Well, if I were you, I’d go to the police station straight away and report it.
W: Yes, I’ve already done that, and they said they’d make a search for it. But we’re leaving soon and I need my visa and identity cards badly.
M: Oh, dear! What a pity! Are you sure you lost the wallet in the theatre?
W: Yes, quite sure.
M: I think you should put an advertisement in the China Daily, saying when and where you lost it.
W: But that takes too long.
M: Wait a minute! I know! How stupid of me. My uncle lives very close to the theatre. I’ll telephone him and ask him to go there. You’d better go and have breakfast and I’ll meet you later.
W: Oh, thank you. That’s marvelous. I hope he find it.
