What behavior of Ellie’s makes Debbie worried?

W: I’m a bit worried about Ellie. She’s nearly six and she still sucks her thumb!
M: Oh, Debbie, you needn’t worry too much about her. I’ve got a friend who has sucked her thumb for twenty-nine years’
W: You’re kidding!
M: No, honestly. She only does it when she’s really tired, but you can imagine how strange it looks on a grown woman.

M: You’re leaving school soon, aren’t you?
W: Yes. My A-levels will start next week, but I’m not too bothered about the results, because when I leave school I’m going to concentrate on my music career. I’m lead singer in a band and I don’t need any qualifications to be a pop star. I see my future very clearly—I’m going to be incredibly famous and fabulously rich.
M: So you’ve already got a contract then?
W: Er, no, not as such. Actually, we haven’t got a manager yet, but the minute I’ve taken my last exam, I’m going to find a really good one.
