I'm glad that story turned out to be fictional, because my bullshit detector was going off through the entire thing. It does do a good job of showing you somebody else's perspective, though.
I think a lot of guys don't quite understand just what some girls have to deal with. I worked with a girl for awhile who was, for most guys, a 10, and got hit on a shocking amount. Shocking to me, anyway. It was normal for her. Dudes even hit on her when she was very clearly pregnant.
From what I was able to observe, the rejections broke down something like this:
25% of the rejected walked away after being rejected, and were nice about it
75% of the rejected continued to proposition after the initial rejection
Half of the 75% walked away after multiple rejections
Half of the 75% resorted to calling the girl a bitch or other such terrible things, then walked away
The point of the article, I feel, is don't be an asshole when you're rejected. Yes, it hurts. But you also need to understand that a lot of girls deal with this kind of stuff all the time, and being nice doesn't mean as much as you think. They get nice a lot. Nice from people with hidden agendas.
Be sincere. If you want to talk to a girl, talk to her. Don't do a nice thing for her so you can guilt or trap her into talking to you.
