I REFER to Sze Shun-ying's letter headlined, ''Now much more positive'' (South China Morning Post, July 23). In a time where student suicides are becoming more commonplace, it is a great relief to see that there are people like Ms Ying, who stop and take the time to address the problems that drive so many people into a confused state of mind. It is good to see that, rather than follow the sometimes misleading messages of many bands and performers today, there are those that realise that there are positive role models out there, and they know what's going on. Although I am not familiar with his music, Wong Ka-kui appears to have been one of these people, and it's good that there are those out there taking notice of people like him.
