IT IS every parent's nightmare - the fear of turning round in a shopping centre to find one's child has disappeared. Or that he or she has left the house on the pretext of an errand, never to return.
Fung Tsui-fung's parents are the lucky ones. She at least has phoned home twice since walking out of the house on November 8 last year. But knowing their 16-year-old daughter is alive only goes some way to easing the heartache.
This is a classic case of the disillusioned teenager - the kind that used to be called a ''runaway'', but who veteran social worker Mr Lau Wing says are now being referred to as the ''stayaways''.
As discontent grows among Hongkong's teenagers, leading to a dramatic increase in suicide, so there is a parallel rise in the number who show their unhappiness by leaving home. A large proportion of the 4,189 people police classified as missing last yearwere teenagers.
By the beginning of this year, 60 of the juveniles were still missing.
Brought up by her father after her mother died 10 years ago, Tsui-fung's previous efforts to run away had landed her in a children's home. It was on a weekend visit to her Shek Kip Mei home five months ago that she walked out with only the clothes on herback.
''How I wish she would tell us where she is now. What can we do except worry?'' her heart-broken grandmother, Ms Choi Bik-kuen, said.
