Sandy welcomes the new neighbours by inviting them around for a drink, little knowing that they're not married. Sandy also tries to interest Oliver into having a holiday by leaving lots of brochures with slinky models laying around.
Oliver joins the Residents Association, while Sandy tries to earn some more money by working at telephone answering messaging, and renting out their empty garage and organizing a jumble sale, all without Oliver's knowledge.
Having to deliver a package to his boss, Oliver gets seen by his colleagues with a succession of different women, including Pauline, who really fancies him. Sandy thinks he's having various affairs as do his workmates.
On the morning before they're due to go on holiday, Sandy wakes up feeling ill. She calls the doctor, and Oliver is forced to miss his going away works drinks to look after her. It seems she's pregnant.
