I read the highest rated comments and no wonder this goes on and on and on.  So many commenters asking what this woman, or that woman, or the other woman didn't do something.  

This is a man problem not a woman problem.  Rather than ask why all these other women did nothing - ask why men accept this behaviour (and puleeze do not tell me "I didn't know") - that is the actual question to ask. 

But stop asking women to solve a mans problem.  Men - deal with your problem.
