DATING is more common than a decade ago, says the 1991 Family Planning Association survey. Here is a sixth-former's view on the subject: Eva Chiu Yee-lin of Tang Siu-kin Victoria Technical College finds dating a highly profitable experience. ''It is a normal and an inevitable part of a teenager's life,'' she said. The 17-year-old comes from a co-educational school and often goes on dates with her classmates. ''In a co-educational school, boys and girls learn to respect each other more,'' Yee-lin told Young Post. ''When we go out together, the boys tend to behave in a more gentlemanly way. The same is true for the girls, they become more lady-like. ''On the other hand, I find students from some girls' schools who, strangely, tend to display rather boyish behaviour and rough manners,'' she said. Yee-lin felt that group dating brought out the best in both sexes. ''A group date offers more opportunities for interaction, which helps us to understand the opposite sex better. ''I have made many friends this way. ''Dating is necessary. It goes a long way in building socialising skills,'' she said.
