A BROKEN leg helped strenthen the bond of friendship that developed among 10 youngsters on a six-day study trip to Singapore last Christmas. The youngsters, aged between 13 and 16, won a youth study programme to Singapore organised by the Boys' and Girls' Clubs Association of Hongkong. In addition to getting to know the education system, community services and beautiful resorts in Singapore, they also learned the value of friendship when one of the members had an accident. Chung Kin-wai, 15, slipped in the bathroom and broke his leg on Christmas day, the third day of the trip. He was sent to the hospital and had his leg sutured. He spent the rest of the trip on a wheelchair. ''It was painful and I was upset. It was also very inconvenient to get around,'' Kin-wai said. ''However, I was touched by my companions who showed a lot of care and concern even though we've known each other for only a few days,'' he added. ''They are even nicer than some of my old friends. The trip taught me the value of friendship.'' Kwok Lai-sze, 16, said nobody complained about having to help Kin-wai. The members displayed team spirit and co-operation. ''We helped him carry his wheelchair, his food and other belongings. Although we are from different schools, we helped each other, just like in a family,'' she said. The accident failed to dampen the group's enthusiasm. They visited the oil company, the airport, a community centre, a leader training school, a Chinese family, and other resorts like museums, zoos and parks. Wai Chun-yip, 13, said he was impressed by the social welfare system in Singapore under which people aged six to 60 have access to all services. Meanwhile, Fung Ka-keung, 13, found the underground traffic system much more modern, convenient and efficient than that of Hongkong. He was especially fond of the accumulated value tickets which can be used for both trains and buses. Lai Yick-hiu, 14, enjoyed the modern airport, which includes not only a hotel, but also a science museum and an exercise room. Ms Eva Ho Yuen-wa, who is in-charge of the study programme, said the participants learned how to live independently and how to be considerate. The trip was also an eye opener since it was their first time in Singapore. The study programme, aimed at raising civic awareness and encouraging young people to participate in voluntary services, is sponsored by the Sir Robert Black Fund and the Committee on the Promotion of Civic Education. The winners were selected from about 60 applicants who had taken part in voluntary services for at least 30 hours. Each applicant was also required to submit a project related to social or community services.
