Many years ago, when I worked as a volunteer at a hospital, I got to know a little girl named Liz who was suffering from a rare & serious disease.
Her only chance of recovery appeared to be a blood
transfusion from her 5-year old brother, who had miraculously survived the same disease and had developed the antibodies needed to combat the illness.
As the transfusion progressed, he lay in bed next to his sister and smiled, as we all did,
seeing the color returning to her cheek. Then his face grew pale and his smile faded.
He looked up at the doctor and asked with a trembling voice, "Will I start to die right away".
Being young, the little boy had misunderstood the
doctor; he thought he was going to have to give his sister all of his blood in order to save her.
