Karen's nice kitchen and nanny would be considered smug in Islington, but north of Watford none of it even raises an eyebrow. Rachel and Adam can quite happily bid a quarter of a million pounds for a flat without being revolting, rich toffs. And David, whose very tricky job entails answering the telephone-importantly, sporting a pocket calculator and plenty of afternoon sex, seems able to support Karen and the three kids in her big fat house, have a bachelor pad of his own, fly club class to Australia, while bidding £250,000 for a property, and have a spare £15,000 in his current account to pay for Adam's flat deposit.
