What behavior of Ellie’s makes Debbie worried? [br] [originaltext]W: I’m a bit

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.

W: I’m so glad that it’s Friday again! What would you like to do this weekend? I’d like to take exercises. How about tennis? I’ve been studying all week, and I’m tired of sitting. Let’s play a few matches.
M: Jenny, I’m tired. Period. I don’t feel like doing anything strenuous. I’d rather stay home and watch movies. Could you stop by the Movie Center on your way here and rent five or six good movies?
W: Come on Michael. I’d rather not watch movies again. I’d prefer to do something active.
