Man: Oh no!
Woman: What is it?

Woman: Oh no, Josh and Henrietta... they’re not that couple who...?
Man: Yeah exactly! And it gets worse...
Man: “Formal dress...”
Woman: Argh.... it means you’ve got to wear a suit....
Man: At the bottom it says “RSVP”. What does it mean?
Woman: You’ve got to reply.
Man: But I don’t want to go, so what can I say?
Woman: Tell them you’ve got a dentist’s appointment.
Man: Josh is my dentist!
Woman: Tell them it’s your grandmother’s 100th birthday party.
Man: But they know my granny died ages ago.
Woman: Tell them your dog’s sick and you’ve got to take him to see the vet.
Man: It’s no use – I’m just going to have to tell them the truth...
Woman: The truth? “I’m not coming to your birthday party because I think you’re boring and stupid?”
Man: Maybe not then...
Woman: Tell them this: “I’m unable to attend because I have a prior engagement.”
Man: “Prior engagement”?! And… they won’t be offended?
Woman: Absolutely not.
