In my wife's case, both women just didn't like being compared because my wife was held in such a high regard and either didn't want to be cast in their shadow because they look like her.
The woman in college with my wife actually jumped my wife and fought her briefly. The other woman backed down the day of after challenging her in person! We never figured out why either. It was day of meeting my wife and after of messaging her and insulting her on FB messenger and then the day came and back down. I'm not sure if it's because my wife never responded and that intimidated her because it's hard to intimidate my wife with words. lol
