     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 goodbye 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 selfconfidence.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."
