Rising above it by ignoring her is a good idea. The more she talks like that the more apparent it becomes that she has MAJOR issues. I wouldn't be surprised if that's the 1st impression that people get and they just smile and nod. That's the first impression I got. If you talk to people there and are polite they will be quick to denounce what this chick is saying.

Those kind of women are very insecure and passive aggressive. She has a huge insecurity problem. Don't feed into it. Instead, fortify yourself by befriending others and trying to have a good time. No time or room for petty small-minded people. Know what I mean? If she sees that it rolls ooff your shoulders even though it still affects u inside she'll have a conundrum that people will see and they'll push her away.

Hope it turns out well.
