Carol : Hello, Sam. Come in.
Tom : Hi, Sam. We're having lunch. Do you want to have lunch with us?
Sam : No thank you, Tom. I've already had lunch. I had lunch at half past twelve.
Carol : Have a cup of coffee then.
Sam : I've just had a cup, thank you. I had one after my lunch.
Tom : Let's go into the living-room, Carol. We can have our coffee there.
Carol : Excuse the mess, Sam. This room's very untidy. We're packing our suitcases. We're going to leave tomorrow. Tom and I are going to have a holiday.
Sam : Aren't you lucky!
Tom : When are you going to have a holiday, Sam?
Sam : I don't know. I've already had my holiday this year.
Carol : Where did you go?
Sam : I stayed at home!
