单选题Sixteen years ago, Eileen Doyle's husband, an engineer, took his four children up for an early morning cup of tea, packed a small case and was never seen or heard of again. Eileen was astonished and in a state of despair. They had been a happy family and, as far as she knew, there had been nothing wrong with their marriage. Every day of the year, a small group of men and women quietly pack a few belongings and without so much as a note or a good-bye close the front door for the last time, leaving their debts, their worries and their confused families behind them. Last year, more than 1,200 men and nearly as many women were reported missing from home---the highest in 15 years. Many did return home within a year, but others rejected the past completely and are now living a new life somewhere under a different identity. To those left behind this form of desertion is a terrible blow to their pride and self-confidence. Even the finality of death might be preferable. At least it does not imply rejection or failure. Worse than that, people can be left with an unfinished marriage, not knowing whether they will have to wait seven years before they are free to start a fresh life. Clinical psychologist Paul Brown believes most departures of this kind to be well planned rather than impulsive. "It's typical of the kind of personality which seems able to ignore other people's pain and difficulties. Running away, like killing yourself, is a highly aggressive act. By creating an absence the people left behind feel guilty, upset and empty." The Salvation Army's Investigation Department has a 70 percent success rate in tracking missing people down. According to Lt. Co. Bramwell Pratt, head of the department, men and women run away for very different reasons though lack of communication is often the biggest motive. "The things that disturb a mall's personality are problems like being tied up in debt or serious worries about work. And some women make impossible demands on their husbands. Women usually leave for more obvious reasons but fear is at the root of it. Men are more often prepared to give their marriage another try than women, but we are aware that, for some wives, it would be a total impossibility to return after the way they've been treated./
