It's terribly tempting to want to wreak revenge if you've been badly kicked by someone you loved. It all depends on what's been before - there was that great story some years back of a wronged politician's wife, who'd stood by him through thick and thin, and had given up working professionally in order to work at home for him. She found out that the little toad had been having an affair for several years. Her revenge, I thought, was particularly imaginative: he'd left the marital home, but asked for his clothes to be sent on to his new address with his mistress. He was sure that his wife was taking things awfully well. She duly sent all of his clothes back, as requested: minus half an arm from all of his suits and shirts, and half a trouser leg from his trews. I can imagine her with some long, sharp scissors, thoroughly enjoying the sartorial amputations.
