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. Hello, 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!
