re: Who's the most annoying office co-worker?

We have a VP level lady that was around when some proprietary software was created and she believes that is how it still works. I used to have to attend meetings with her and I would have to correct her constantly that we have made changes but she was too stubborn to admit it, so I'd go test functionality and take her the results then she would go on about how why did we do this and a bunch of other meaningless questions.
