dialogue: M: Rebecca, I've come to say sorry to you. W: Why, Peter? M: I can't find the dictionary you lent me. W: Don't worry, Peter. Maybe someone is using it now. M: But nobody is in the classroom now. W: Well, nothing serious, Peter. It's only an old dictionary. M: I'll buy a new dictionary for you. W: No, I won't hear of that.
