“Of course the thing would have to be done furtively and politely,” said Clovis; “the charm of it would be that it would never be perfunctory like the other thing. Now, for instance, you say to yourself: ‘I must show the Webleys some attention at Christmas, they were kind to dear Bertie at Bournemouth,’ and you send them a calendar, and daily for six days after Christmas the male Webley asks the female Webley if she has remembered to thank you for the calendar you sent them. Well, transplant that idea to the other and more human side of your nature, and say to yourself: ‘Next Thursday is Nemesis Day; what on earth can I do to those odious people next door who made such an absurd fuss when Ping Yang bit their youngest child?’ Then you’d get up awfully early on the allotted day and climb over into their garden and dig for truffles on their tennis court with a good gardening fork, choosing, of course, that part of the court that was screened from observation by the laurel bushes. You wouldn’t find any truffles but you would find a great peace, such as no amount of present-giving could ever bestow.”
