Barbara Walter is a well-known TV documentary person in the United States. She did a documentary on trans kids in April 2007, and when I saw it on You Tube I cried. Now the scientists tell us that tears of joy and sadness have different chemical compositions, well my tears were very mixed in their composition. I cried tears of sadness for these children who have had to go through what I went through. They just want to embrace their gender identity, but society will not permit this. I cried tears of joy for the support they were getting from their parents and schools. And I cried tears of regret that I waited until my twenties to tell anyone else about my gender issues and only really started telling people in my 40s.
