Hi, my name is Marc, and I cheat on my wife. No, no, no, not in a bad way, I promise. I have a work wife. Actually, I have two work wives, and my wife knows about each of them. What, you may ask, is a work wife? Well, it is a co-worker, usually of the opposite sex, with whom one shares a special relationship, having bonds similar to those of a marriage. You may be wondering how these relationships developed.
