some saint once said, men are keys, women are keyholes, perfect marriage means a key perfecly matches a keyhole. one fact that many people always forget is that keyholes are constantly changing. so the key is that you have the right key for the keyhole anytime needed. considering they would be together for decades, to make sure mr cui has all kinds of keys would be some kind of guarantee to happiness of mr & mrs cui.
