Mark: Hello, Jenny. What are you doing here? Jenny: Hello, Mark! This is my daughter, Sarah. It's the school holidays so we're shopping now--- we're not sure what to do after that. Mark: Well, there's a show for children this afternoon in the library where I work. Jenny: Oh'? What time is it at? Mark: It starts at two and finishes at three thirty. It's only a quarter past one now. Do you think Sarah would like that? Jenny: How much is a ticket? Mark: Well, it's one pound fifty for adults and seventy-five pence for children. Programmes are twenty-five pence. Jenny: And does your library run a reading course in the holidays? Mark: Yes, and if children under ten, like Sarah, read four books in six weeks, we give them something to take home. Jenny: What, like a book? Mark: Well, this year it's a pen, but sometimes it's a book or a school bag. Meet me after the show and I'll give you some more detail. Jenny: Thanks. See you later then.
