I had one ... at my previous job ... actually I never gave it much thought and I don't think he did either ... it was his wife who gave me the title .... and it made sense to both of us once she had done so ... funny thing was that she was a wonderful woman, but very jealous ... of anyone and everyone and not because of him ... her father had been a major "player" .... (got sidetracked there) ... anyway, because of both his and my personalities and life-style choices, I was probably the one woman she was never really jealous. It worked well for all of us ... I always made sure he remembered her birthday, their anniversary ... gave him possible suggestions for gifts for different occassions, he had a place to vent (without giving too many details) about her idiosincracies and so did she ... I think I was really the office spouse to both of them come to think of it!
