Not RTFT but wanted to add something I saw some years ago.
A little girl...probably about 11, had cancer. It was successfully, if brutally, treated but it came back. She had tumours everywhere and although the doctors could prolong her life with Chemo etc, her parents decided against it. The previous treatment had been so hard on her, she had be isolated, missed her siblings, missed playing out and having fun and hated what the treatment did to her. It would probably have bought her months rather than years.
Her mother was asked if she had told her DD and she said no. She said that it was a decision that no 11 year old should have to make and that although it broke her heart knowing that she was deciding that her DD's life was going to end sooner, she was a mother and part of that job is making tough decisions so your kids dont have to.
I cried and cried watching it, but the little girl was so happy playing on the beach, far happier than she would have been spending her remaining time on a drip in a hospital bed. She died a few months later, but I am sure that the wonderful times they had before she died were a comfort to her parents. I believe that the mother was right, she did the hardest thing she will ever have to do, in order that her daughter didnt have to deal with "hospital or death". For that reason I think that these parents are very very wrong.
