Riding my bike in traffic, I sometimes see car drivers do things so dangerous that it brings my blood to a boil, and I chase them down and yell at them. Looking back on it later, I've wondered why I lost my cool. Not that I get violent; but emotion definitely overpowers self-control. In light of this... and I didn't see it the first time I watched the video... but the girl who got her ponytail yanked had a whole fistful of the other girl's shorts in her hand at the time. As I sometimes have to say to my kids... "well, what did you think was going to happen, if you did that?"
