Helen : Isn't there anyone at home?
Jim : I'll knock again, Helen. Everything's very quiet. I'm sure there's no one at home.
Helen : But that's impossible. Carol and Tom invited us to lunch. Look through the window.
Helen : Can you see anything?
Jim : Nothing at all.
Helen : Let's try the back door.
Jim : Look! Everyone's in the garden.
Carol : Hello, Helen. Hullo, Jim.
Tom : Everybody wants to have lunch in the garden. It's nice and warm out here.
Carol : Come and have something to drink.
Jim : Thanks, Carol. May I have a glass of beer please?
Carol : Beer? There's none left. You can have some lemonade.
Jim : Lemonade!
Tom : Don't believe her, Jim. She's only joking. Have some beer!
