TWENTY years ago, Yuen Chi-shing's mother sat him down with a babysitter, walked out the door and never came back.
Today, after fruitlessly searching for his birth mother, Chi-shing is legally able to call the babysitter 'Mum' - thanks to an August 3 Family Court decision allowing him to be adopted.
Mr Yuen, a Form Five graduate working in a bookshop, said: 'Although I do not know who my natural mother is, I am glad to have a mother now.
'I am grateful to her. She had no obligation to look after me; she was not paid but she brought me up and paid for my school fees.
'She is a great mother. I am lucky and proud to have her caring for me.' Twenty years ago, Mrs Yuen, 58, met a woman in a playground in Po On Road, Cheung Sha Wan, and was asked to look after a one-month-old boy without pay.
The woman visited the child once or twice then disappeared.
