I have been twice Summer, first time with OH, second time with ED when she was about 15. Both times left me unable to speak for quite a while (and that doesn't happen often) I think it was because I had read her diary, seen documentaries etc and it was so real. Everything was exactly as she described. When I was a teenager the same age as she was when she was hiding I identified with her - same name, same spelling, and I wasn't very happy either, although far from her level of suffering, and then I was standing in her home reading the words on the actual paper, looking at the pictures, even the toilet she described so vividly. I think its one of the things everyone should do once.
