Dear Mary | 17 November 2016

Q. Following a lavish house party I received a flood of effusive thank-you letters, the bulk of which praised the impeccable service, the luxurious treats laid on nightly, and my attentiveness to my guests’ every whim. One letter, however, commenced in a fairly complimentary vein but soon devolved into a letter of complaint about a fellow guest. So vehemently did the author express his antipathy that he covered two sides of paper. I concede that the young woman in question is an acquired taste, but I resent my friends being subject to character assassinations. How can I reprehend the scribe?

A. Bear in mind that this letter is something of a compliment. The author defies convention to put your welfare above his own. In speaking his mind, he risks his own exclusion from future house parties. If you still wish to punish, invite him to an ‘acquired taste’ restaurant such as Quo Vadis on Dean Street, not mentioning you have also invited the subject of his scathing diatribe.
