David was just a child, a human being. He suffered his entire life trapped in a very small plastic bubble. As the numan being he was, he got mentally ill, yet, he remained aware and despite bouts of dispair, he didn't entirely lose hope until the very end. David had to be strong and courageous in a way most humans don't have to be. I am so glad he had Mary Murphy by his side, validating his reality in a way no one else would. It was an extremely sad and lonely existance. First he was treated like an experimental animal while trapped in a bubble; second most Drs, the media and even his parents chose to believe he was ok in a bubble. No one in their right mind trully believes he was a "happy child". Are encarcerated people content to be confined to a small space? Research indicates not. It's horrible for inmates, it's even worse for a little child. It has devastating effects on a child's development. That's humanity 101. I hope David has found freedom wherever he is. I hope he is in a place now where he can thrive, be happy and have a decent existance.
