The "Secretary"

I have a new title at work. This title has been granted to me by a co-worker that is younger than me and a little mentally challenged. She likes to call me "The Secretary".

Maybe I'm not "hip" or "with it", but as far as I know, the title "secretary" went out in the late 70's. It's a very degrading term, sexist and painfully outdated.

This girl insists on calling me a secretary. After working there for 3 weeks and 2 days I'm a little shy about confronting her with the problem, but whenever she uses the term it makes me want to spit nails into her eye sockets.

If I recall, the actual title of my position was "Customer Service Rep".

Does anyone out there have a suggestion on how I should confront this young lady without knocking her teeth out?

Please help!!!
