Francis Scott Fitzgerald was right. The rich really are not like us. I was reading funeral announcements put out this week by the families of late tycoon Lim Por-yen, who is to be buried today. One was published jointly by his first and second wife, their children and grandchildren. You can guess at the family drama there, seeing how the third wife, Koo Siu-ying, and her socialite daughter Pearl Ling Ming-chu, were not mentioned. The latter two had to put out their own notice two days later. It's puzzling just how many wives you are allowed to have under common law in Hong Kong. This isn't the first time I was confused. Can you, for example, really describe Angela Leung On-kei (pictured) as the fourth wife of casino mogul Stanley Ho Hung-sun when the others - except for his late, first wife Clementina - are still alive and undivorced? Every newspaper in Hong Kong describes her as such, but it's still cause for confusion. But as a married man, I can vouch that monogamy laws are for the good of ordinary mortals like us. Face it, unless you've got a few million dollars in the bank, you really can't afford more than one.
