I've always found that when you act as if you are not miffed, it drives the other person nuts. If she intended to be condescending, don't give her the satisfaction of being obviously hurt, or irritated.
Years ago I had a small team of nine young people (AirForce and fresh out of collage newbies). Two of those people (young/immature) who liked to stir things up. One of the young women started telling me about how another team chief would do an impression of me at parties that she thought was hilariously funny. Apparently Marion would mimic the way I sat in a chair, or how I would absently brush my hair back when it got stuck in my collar......my immediate thought, and what shot right out of my mouth was "OMG, I must drive her crazy, I wonder why she is so obsessed with me" . Apparently that wasn't the reaction she was expecting, she wanted discord but all I felt was pity for both of them that they were so stupid as to tell the person who wrote their performance appraisals and recommendations for promotions and awards something that would not be a positive point for them. (Plus I enjoyed the confused look on the young woman's face)
As far as the person who annoys you, the fact that she made an immature observation in front of the boss and entire team speaks poorly of her, and everybody noticed. You have an opportunity to be the class act by not responding to her provocation or her digs........by not reacting you prove she has no power over you at all. I promise you, that will drive her crazy.
