Those pictures were taken with her knowledge.
I can say one thing for sure now, after many stories. Girls with long hair love to be complimented. DO NOT be afraid of going and talking to them. In the case of this girl. I got to touch her hair, play with it, tug on it a little bit and even buried my face in it.
Guys, if you see something you like, do for it. Make sure you ask first and you are nice....dont be creepy
