Police work is stressful and dangerous. It can put a heavy strain on married life. This, presumably, is why the force has been engaging the services of the Hong Kong Catholic Marriage Advisory Council to help out married officers. A recent family life education course run by the council's Fok Yuk-lin for officers gives some intriguing examples to spice up marriages under stress. First participants have to think of a beverage that best describes their marriage. 'Would you say it tastes like wine? Or harshly bitter like coffee. Or rather plain and tasteless, as water?' Fok writes. 'Would it be like the pearl-barley water that works best for whetting the appetite? Or perhaps it's as good as chrysanthemum tea.' She describes this as 'the taste of marriage', which, properly chosen, helps people better understand their marriage. Fok's background, like her husband's, is in theology. Her 'art of love', understandably, makes no reference to sex. Perhaps just as well. We should love as our spouses want to be loved, she sagely advises, not how we want to be loved. In Fok's case, this means cooking a lavish dish of steamed eel and sauteed crab with ginger and scallions for her husband. Alternatively, she says you may try writing 'sweet messages' for your loved ones before you leave for work. 'We may leave a sweet message on toilet paper towels for our sweethearts,' she suggests - and I'm not making this up. Personally, I find this impractical, especially in the morning. Most half-awake people use toilet paper for just one purpose in the morning.
