I completely agree with Doug Giles. I loathe bullies and the best way to deal with them is to call their bluff. If that women had gotten right back in their faces, the wind would have been knocked right out of their sails. Instead she became their victim and oh, man, do bullies like victims. Because neither she nor the bus driver or other students for that matter stood up to them, everybody came away with a very negative experience that will linger for a long time.
