One thing is you don't mess around with those you work with. It is nothing but trouble. Secondly, I'll take intelligence. You have to be able to communicate with your spouse. Can you imagine trying to carry on an intelligent conversation with someone like Paris Hilton. All the money in the world won't buy her brains and sooner or later the beauty runs dry. In her case I think it already has.
You're right. Regardless of the screaming of my loins, the one requisite is intelligence.
Why do you think it is a mistake to date people from work? Some of us only know relatives and workmates.
