"I would walk through a tunnel of fire if it would save my son. I would take my chances on a stripped battlefield with a sling and a rock à la David and Goliath if it would make a difference. But it won’t. I can roar all I want about the unfairness of this ridiculous disease, but the facts remain. What I can do is protect my son from as much pain as possible, and then finally do the hardest thing of all, a thing most parents will thankfully never have to do: I will love him to the end of his life, and then I will let him go."
