A woman in Paris said yes to every single man that spoke to her as an experiment for two weeks. She did it in part to delve into the psyche of men that feel they can talk to anyone they want, and to see if they understand how annoying or scary it can be to those on the receiving end:

You see, I had decided to conduct an experiment wherein I would say "yes" to and engage in conversation every stranger who hit on me for two weeks. I wanted to get into their heads, find out who these men are, if their tricks worked and, perhaps most importantly, if they are aware that the majority of women find what they are doing incredibly fucking annoying and more than a little bit creepy.
