In the library
Johnny – Hello. This is Johnny. May I talk to Sue?
Sue's mother – Hello, Johnny. This is Sue's mother. How are you?
Johnny – Fine, thank you. And you?
Sue's mother – Fine. I'm afraid Sue isn't at home. The literature teacher has asked her to write a composition about Oscar Wilde and she might be in the public library.
Johnny – In the library?
Sue's mother – Yes. I don't know exactly what she is doing there. She may be looking up some information about the author.
Johnny – But there's a library at school, too.
Sue's mother – I know, but it's closed now and she might need more information. You know. She could just need a quiet atmosphere.
Johnny – I've never been to the public library.
Sue's mother – Sue says it is very good. There is a microfilm reader and a photocopy machine and there are also lots of interesting magazines. Sue says that the librarian and the library clerks are very nice. They help you in everything.
Johnny – I may go to visit Sue and help her.
Sue's mother – She will be happy. But remember I'm not sure she is there.
Johnny – Ok. I'll try to meet her. Nice to talk to you.
Sue's mother – Bye.
Johnny – Goodbye.
