Actually I am not ready to file this under inappropriate. It really depends on the context of the situation. At the same time, however, she ought to have taken heed of your reaction to what was said. If such a thing happens again, then the matter IS a case of harassment and you should take steps to curb it from happening yet again. If you can't talk to her directly then do so with the person who manages her. In the meantime, this is definitely something to explore with your therapist.
