Samantha Hanahentzen, 17, poses for a #MeToo portrait in Detroit, Michigan, U.S. October 29, 2017. Hanahentzen said: "When I saw the #MeToo hashtag I was just coming to terms with my sexual assault. It happened when I was in middle school by one of my teachers. It took me a while to come forward with what had happened to me and then when I went to the administration I was told I didn't have enough evidence to prove anything and I should just keep quiet about it because I and the school could be sued for slander if I went public with my experience. It was really silencing because when I was being assaulted it was that stereotypical line of 'let's keep this between me and you.' And then when I found the courage to come out with it I was told again 'let's keep this quiet.' So for me too, it was a way to have a voice and it was a way for me to see that I'm not the only one that has gone through this and that women all around the world have all experienced the same thing. It was really unifying." REUTERS/Lucy Nicholson
